I have a requirement to integrate Trello with our Office 365 tenant so that our users can use your application to attach OneDrive documents or use the OneDrive Power-Ups to bring files or folders to Trello cards. To do this, we would require to register your app into our Azure AD Environment.
Our Environment is secured and restricted for registration and use any third party application unless those applications are developed considering the Microsoft Admin Consent framework.
Please let us know if your application support the Azure AD consent framework and if so please share the required consent URL which could possibly provide us information and help us to register your application in our environment.
