I'm stuck on this trailhead. "Activate Session-Based Permission Sets Without Code"

I believe I did everything correctly.  I get "Challenge Not yet complete... here's what's wrong: 
Permission Set 'Temporary Account Edit' is not referenced in the flow 'Accounts Temp Access'. Check the instructions"

I can run the flow successfully, and I can confirm via setup audit trail that the permission set activation occured.
