I was thinking about this when a colleague ask if I saw him in the file. I was in another file that has similar prototypes and searching for him and didn't find him. Then, I realized that I was in the wrong file and started to look through the teams, projects, files, so I could find him.
What if, there’s a invitation to file, where I send it to a person and they receive the invitation by the notifications menu, where they could accept or not.
This could save a lot of time in meetings.
