Just a suggestion @techno-disaster, i think it would be great if you can add this search functionality to that search symbol which is there on the right of the Members tab [and left of the settings button]. So that on just clicking that symbol at the top, one can directly do the searching of members.

@robotjellyzone yes, I planned to do that before but if you check mentorship-androod repo it was decided to have a new page for search functionality. This helps in UX.

@robotjellyzone would you mind adding this test to TestQuality. Ping me if you need help.
