[Linking to already created DB 2] Obtaining and setting up database ID
Copy the link to the database for which you set the permissions for integration in "[Linking to already created DB 1] Database share settings".
The URL is in the format https://www.notion.so/[domain name]/[DATABASE ID (32-digit string)]?v=[VIEW ID]. The string before the ?v= is the DATABASE ID, so only that part of the string should be retrieved.
(e.g.) If the copied URL is https://www.notion.so/domain-name/3956b991ea4a4b90b893f3abd1ed054b?v=2e8ed026e08b48e3a7b0fe7ad6150be8, the DATABASE ID would be 3956b991ea4a4b90b893f3abd1ed054b.
Enter the obtained DATABASE ID into BookNotion and click "Link to Database".
Once the databases are linked and the page ID and database name are automatically retrieved, the database change is complete.
You may not get a page ID, but this is not a problem and you can use the page as it is.
Good job on the linkage to the created DB.
