Processes in Microsoft 365 for setting up Office apps, redeeming product keys, and activating licenses.
Dear Marenka,
Good morning, thank you for inquiring in this forum.
From its description, it appears that you are using API with Copilot Studio to create a custom plugin and you have some questions about it.
If my understanding is correct, we would also love to help you, as our category focuses on general troubleshooting and features built into Office 365 business products, the question you mentioned is related to Copilot Studio and API, we suggest you go to the related community
Microsoft Copilot - Microsoft Q&A to post a new thread, which is a specific channel to monitor the situation.
If my previous interpretation isn't consistent with yours, you can also repost it and point it out.
Your understanding and patience will be greatly appreciated. I hope you stay safe and sound!
Sincerely
Sukie | Microsoft Community Moderator
