Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Hi Nesma,
We went through your post carefully, it seems that you, as the tenant admin, want to have a restriction group policy to apply for allowing only specific users access to Copilot Studio.
If my understanding is right, since the query is related to Copilot Studio and to avoid any incorrect information from community moderators here that mainly focus on Copilot in Microsoft 365 like Office apps, we’ll suggest you post in Microsoft Power Platform - Copilot Studio Community Forum for expert assistance as suggested in **** Find community help and support - Microsoft Copilot Studio. There show several support channels for Copilot Studio platform, you will get the most qualified pool of respondents to provide you the available resolutions.
Please let me know if there have anything I can do for you.
Appreciate your patience and understanding and hope you stay well!
Sincerely,
Mia
