Was able to link it just now!I did this:
"Select Temporary Residence first, then work permit and extension.
Application details: UCI and family name. (Use principal applicant data)
Applicant’s personal information: Place of birth. (Input what you wrote in the application form)
Details of intended work in Canada: Open (initial application or extension).
Current Country of residence: Canada.
Current marital status: Married or whatever applies.
Which situation applies to the applicant: Applied for permanent residence as a spouse or common-law partner in Canada.
If place of birth option does not work, try using passport info." ------Copied from other member P52
For the UCI, I used the UCI associated to my wife, not the one in the AOR (which is mine).
