Fabric Data Agent Access issue

I have created a fabric data agent using semantic model of a published report,
It is working fine but I'm not able to share it with others
I published the agent in M365 copilot and share with my teams of 100 people

only 4 or 5 people can go to M365 copilot and search the agent and added the agent to their agent tab others are not even seeing the agent
but if I share the agent link from M365 copilot then they see the agent but agent is not answering the questions but it's perfectly answering for me and other 4 to 5 people who see the agent

when I surfed it said it said there are 2 level of access to get answer from the agent
1. agent level access
2. underlying data level access

I have workspace contributor access for workspace, read, write, reshare permission for the agent. most of them share the same access but there are not able to see
the only difference I found is I'm having premium per user license and most of other have pro license so I doubted it but internet says license is not an issue

can anyone pls help me with this issue
