Check feasibility of Requests

[timea-solid]

In the new design we have requests on the friends tabs.
However, it is not clear if we can implement this feature at all. It is maybe impossible to know if someone is linking to me as a friend. Need to check.

In order to implement Requests we will need to implement inbox features. We have some helper code in solid-logic here and we have inbox functionality in chat here I'd love to research how to store the data and create a ticket for that. Would be awesome to have it.
