Add "Mention user" button to user profile

https://pleroma.gnusocial.club/users/9lsXzLOaQZgNoIumQK

on this link I would for example post a notice to this user, but there is no option. Of course I could mention user directly from status form, but there shall be some small icon "Mention" or "Notice to user" or similar directly from the page, isn't it? It will increase communication.
