'Unknown Error' when connecting to the Excel Online (Business) connector in Logic Apps

When I try to add an action from the Excel Online (Business) in a Consumption Logic App, I get 'Unknown Error' after signing in using my Microsoft account. I've tried in other browsers and in private mode, same for all. And same with the SharePoint connector and Word Online connector. I've seen on another post that it might be a permissions issue, but what permissions would I need? I have Contributor on that Resource Group and I don't have this issue with any other connectors. Also I can add that connector in Power Automate no issues.

    I logged out and logged in again in the pop-up and then it worked!

    Are you perhaps not able to create a connection reference in the connector? I have had similar issues in Power Automate where I would have to create a connection reference separately first and then use it when I create a flow. The problem I ran into at the time was that a popup blocker would prevent me from signing in and completing the authentication.
