@Joseph Alan Smith
Are you referring to "Enable Relationship Viewing", with another User/Patron?
IF, so; THEN ...
There are two ways that I know of:
One is through your "Settings", under the "Contact" 'Tab', in "FamilySearch".
The other is when you select the "Contact Name" of a User/Patron who has contributed details to a record.
IF, not; THEN, please explain/advise ...
I hope this helps.
