This is an original TIM page and cannot be modified. But a custom page of this one can be create, with a different name.

Choose where to create the new custom page:
if it is created in the Space all the users that are sharing this space can use and edit it, but it will not be available in other spaces.
Otherwise, if it is created in the User settings, the custom page will be available in all the spaces but only for you.

When the new page is available, just use the edit button again.
