Custom post pagination links

I’m not using blocks.. I need some type of hook or function to completely customise this part from child theme functions.php:

		<nav <?php generate_do_attr( 'post-navigation', array( 'id' => esc_attr( $nav_id ) ) ); ?>>
			<?php
			if ( is_single() ) : // navigation links for single posts.

				$post_navigation_args = apply_filters(
					'generate_post_navigation_args',
					array(
						'previous_format' => '<div class="nav-previous">' . generate_get_svg_icon( 'arrow-left' ) . '<span class="prev">%link</span></div>',
						'next_format' => '<div class="nav-next">' . generate_get_svg_icon( 'arrow-right' ) . '<span class="next">%link</span></div>',
						'link' => '%title',
						'in_same_term' => apply_filters( 'generate_category_post_navigation', false ),
						'excluded_terms' => '',
						'taxonomy' => 'category',
					)
				);

				previous_post_link(
					$post_navigation_args['previous_format'],
					$post_navigation_args['link'],
					$post_navigation_args['in_same_term'],
					$post_navigation_args['excluded_terms'],
					$post_navigation_args['taxonomy']
				);

				next_post_link(
					$post_navigation_args['next_format'],
					$post_navigation_args['link'],
					$post_navigation_args['in_same_term'],
					$post_navigation_args['excluded_terms'],
					$post_navigation_args['taxonomy']
				);

			elseif ( is_home() || is_archive() || is_search() ) : // navigation links for home, archive, and search pages.

				if ( get_next_posts_link() ) :
					?>
					<div class="nav-previous">
						<?php generate_do_svg_icon( 'arrow' ); ?>
						<span class="prev" title="<?php esc_attr_e( 'Previous', 'generatepress' ); ?>"><?php next_posts_link( __( 'Older posts', 'generatepress' ) ); ?></span>
					</div>
					<?php
				endif;

				if ( get_previous_posts_link() ) :
					?>
					<div class="nav-next">
						<?php generate_do_svg_icon( 'arrow' ); ?>
						<span class="next" title="<?php esc_attr_e( 'Next', 'generatepress' ); ?>"><?php previous_posts_link( __( 'Newer posts', 'generatepress' ) ); ?></span>
					</div>
					<?php
				endif;

				if ( function_exists( 'the_posts_pagination' ) ) {
					the_posts_pagination(
						array(
							'mid_size' => apply_filters( 'generate_pagination_mid_size', 1 ),
							'prev_text' => apply_filters(
								'generate_previous_link_text',
								sprintf(
									/* translators: left arrow */
									__( '%s Previous', 'generatepress' ),
									'<span aria-hidden="true">&larr;</span>'
								)
							),
							'next_text' => apply_filters(
								'generate_next_link_text',
								sprintf(
									/* translators: right arrow */
									__( 'Next %s', 'generatepress' ),
									'<span aria-hidden="true">&rarr;</span>'
								)
							),
							'before_page_number' => sprintf(
								'<span class="screen-reader-text">%s</span>',
								_x( 'Page', 'prepends the pagination page number for screen readers', 'generatepress' )
							),
						)
					);
				}

				/**
				 * generate_paging_navigation hook.
				 *
				 * @since 0.1
				 */
				do_action( 'generate_paging_navigation' );

			endif;
			?>
		</nav> 

With link I want to add some custom meta and other items…

exactly, since I’m not using blocks.. just need some hook or function that will access navigation part so I can add my own code there…

Ok that makes sense.. I will try that approach.. Thanks
