We want to collaborate with Confluence within the Teams application. We followed the instructions below, but the page still fails to show information, just blank page. It would flash a message that the permission within Confluence is not enough but we're admin and can definitely see the page within the Confluence site. It's working within the Teams web client without any error though.
Add an existing Confluence page
If you have multiple Confluence sites, you'll need to choose which site to search for pages from.
Select Teams tab in the left panel.
Select one of your channels.
Click + in the top right.
Click Confluence Cloud for Microsoft Teams app.
Select Attach page.
Search by title or choose a recently viewed page.
You can select Post to the channel about this tab.
Select Save.
Is there something we need to add in Teams admin to permit Confluence cloud? It is already configured to be allowed.
