Decide on an activity and format for the upcoming usability research in Brazil and Mexico

We're planning on launching a call for participation for the next remote training session, scheduled to happen in Brazil and Mexico at the end of March/beginning of April. Let's use this ticket to decide how we'd like to structure our user research (e.g. as one-to-one sessions with participants following the training workshop), pick the activity we want to run and discuss any amends to that activity (if required).
