[FEAT] Add a delete button to delete a family member

[Aleksander]

Is your feature request related to a problem? Please describe.
Currently there is not way to delete a family member once added.

Describe the solution you'd like
A button besides the user to remove the user

Describe alternatives you've considered
I've considered using a input text to delete the user by name, however a dedicated delete button seems to be a better approach.
