Approval required

My organization has Anaconda Business plans, and recently i have sent invitation to one of the colleague.
He used the accepted invitation link in the invitation email, sign in with Microsoft account and company email address, next there is a prompt saying

Approval required
Anconda, Inc
This app requires your admin’s approval to:
View user’s basic profile
Maintain access to data you have given it access to

he provided the justification, and click “Request approval”
But i am wondering where this request approval goes, as i did not received anything to approval, despite i am the administrator of my company’s Anaconda Business license.

So this is due to the way SSO flows work. When you are clicking something like “Sign-in with microsoft” you are generally using an OAuth client that has been set up to use general microsoft accounts, so outlook accounts or 365 account. What you likely have is an account that is managed by Azure, which is a different OAuth client, and one that is not generally available. So, the general default microsoft client has to contact your azure client and ask for data, as it does not have permission. This is where the approval request comes in, since it needs general metadata about your client, the admins of your client have to approve the app’s access.

This process is generally referred to as ESSO or Enterprise SSO, which would need to be pre-configured by your admins and Anaconda.

To answer the question directly, the request would go to whatever email is an admin in the Azure/Entra instance that manages your enterprise identities.

thank you @zfralish for your reply.
i tested sending invitation to another colleague, he didn’t the the “Approval Required” prompt.
hence for this affected colleague, i revoke his invitation, resend invitation, and this time he is able to accept invitation without getting the “Approval Required” prompt.
Case could be closed.
