Can I use a subdomain?

Hello, can I use Generate Press/Generate Blocks Pro on a subdomain?

I have two sites: abc.com and blog.123.com. They are completely unrelated.

I use Generate Press/Blocks on abc.com (a regular domain).

I installed Generate Press/Generate Blocks on the other site (blog.123.com). The Generate Blocks license key is active on this site, but in the WordPress dashboard, under Generate Blocks < Settings, I don’t see any of the modules.

Am I able to use Generate Press/Blocks with a subdomain such as blog.123.com? Or does it have to be a regular domain, like abc.com?

Notes:

1. abc.com and blog.123.com are completely unrelated.

2. I cannot use the regular 123.com domain, as it’s a Shopify store. I would like to use a WordPress blog for the store rather than the built-in Shopify blog.

Thanks for your help.
