only a long click on the time will open the message menu
it should also work for the message itself

[sowjanyakch]

the problem with links still exist - long click on links open both message menu and link. I will handle it in a different PR.

[sowjanyakch]

the problem with the long clicks is solved. I implemented this in the same PR. Needs to be implemented the same solution for #5533, #1789

/backport to stable-23.0
