A web-based tool in Microsoft 365 that enables users to quickly create surveys, quizzes, polls, and feedback forms.
Dear Zhang Junwei,
Good day! Thank you for posting your query in our community.
As per your description, it seems that you want to add the" Copy" function in Microsoft List app button line directly for easier use.
If my understanding is right, as forum support, we don't have enough permission and resource to connect with the develop group.
Given this situation, we'd sincerely recommend you contact your office 365 administrator to go to Office 365 Admin Center-> Support-> New Service Request. The engineers in related team have higher permission and resources than us, and they have the escalation channel to contact the product group and raise a Design Change Request as per your need. This is the most efficient way to resolve such issue.
Please refer to these articles for the way how to raise a ticket and how to find admin: Ways to contact support for business products - Admin help, How do I find my Microsoft 365 admin? - Microsoft Support.
Your understanding and patience will be highly appreciated. We hope that you are keeping safe and well!
Sincerely,
Rhoda | Microsoft Community Moderator
