Hi,
It turns out that the admin of the Azure AD has probably deactivated the possibility for non-admin users to consent apps to accessing data on their behalf (a.k.a. delegated permissions)
For example, here is our setting at SonarSource (so we don’t see the kind of prompt that you saw)
As a reminder, we are using only permissions that are grantable by non-admin users.
So the solution might be to probably ask an admin for either trigger to Yes the first option on the screenshot, or consent the app for the whole tenant by login on SonarCloud.
Let me know.
Thank you.
