Hi Kristiana,
You need to add Standard Controller = User on your visualforce page for it to be visible here. Example below
<apex:page standardController="User">
-- SOME MESSAGe --
</apex:page>
Once you have this, the page should be available for you in the layout.
Best,
Vishal
Thank you Vishal and Anutej for Answer.
This approach works -
<apex:page standardController="User">-- SOME MESSAGe --</apex:page>
