How to search Teams communication only between 2 users?

I'm trying to query teams chats and calls where 2 users are communicating with each other.

I tried the suggestion here: [Microsoft Teams eDsicovery case between two users : r/sysadmin](https://www.reddit.com/r/sysadmin/comments/16lr4yl/microsoft_teams_edsicovery_case_between_two_users/)

However, I keep getting all results where one or the other is a sender or recipient of any message rather than the results being limited to the ones where they are both in the same communication.
