"Friends" tab search should let you search by note text

I have many friends on Discord who I met either IRL or on another website. Often their discord handle is different from the handle they use elsewhere. To help myself remember who is who, I will use the "Note" feature and note their IRL name, Twitter handle etc. However, if I go back later in the "Friends" tab and search for the name I entered in the note, the "Friends" tab does not find it. The only way to find someone by the name in their notes is to right click every single person I follow and read the note until I find the person I'm looking for.

Expected behavior: The search in the "Friends" tab under DMs in the web app, or under "Find or start a conversation" in the phone app, should match on text in the user-defined note (or offer an option, for example, in the phone app "filter options", to search my notes).
