Meet Now Chat History in "Collaboration with Teams" mode

Hello Community!

our users are using Teams in "Collaboration with Teams" mode. They use the meet now feature to quickly have a conversation (Audio, Video, Chat). 

How is it possible to open the chat history after the meeting was closed? When I search for keywords from the meet now chat, I can see it in the search results but can not open it here (longer messages are not fully visible here).

Can somebody tell us how this is possible?

Thank you and Kind Regards
