Hi, I recently started using SuperTokens, its great! I wanted to implement the following scenario: 1. I have multiple sub-domains having different databases. 2. I have a self-hosted Supertokens core. 3. I want to create a single login server using supertokens so that a session created in the login server is shared by any subdomain. So can I do that? I mean I will connect multiple backends with the same supertoken core and use the login server as the entry point Any other suggestion will be great.
