Embedding Google documents with restricted access
Viewing Google documents with organization or restricted access requires an authorized Google account and consequently, the ability to log into such account.
However, Google’s support to external authentication is currently limited.
If a user tries to view a restricted document through an embedder app and they’re NOT logged into any Google account, Google’s login screen won’t show up and instead a generic error will be displayed.

To fix this:
open a separate tab and access any Google product
log into your Google account
go back to Jira/Confluence or monday.com and refresh the page
