[Feature Request] Search - filter sender

[realgrm]

Is your feature request related to a problem? Please describe. Sometimes I remember something important a person X sent about a subject Y. Since I cannot filter the person who sent the message, when I search for Y, it returns a lot of useless messages for my research. The problem escalates when this person is in a lot of groups as same as me and I don't know in what group this message came from.

Describe the solution you'd like Be able to filter the sender from the results of a group and global search.

Describe alternatives you've considered Be able to only filter the sender from the results of a group search, since is already implemented in the desktop (and Android and iOS) version.

Additional context Implementation in the desktop version in the group search.
