Hi @Prajwal Shenoy,
Thank you for contacting Q&A Forum. I would like to provide my findings and proposed solution:
The error message is "Insufficient privileges to complete the operation." which means lack of roles or permissions. Please contact RadiantOne vendor to provide their official configuration document which includes Entra ID roles and permissions they needs.
Kindly let me know if this work for you and please let me know if you have any further questions.
If I have answered your question, please accept this answer as a token of appreciation and don't forget to give a thumbs up for "Was it helpful"!
Best regards,
Eric
