Tacx smart training app with FTP tests

hey everyone,
Any of you using the Tacx training app, how do you perform your FTP tests? Do you just wing it based on the intervals you know you need to do and calculate it later, or do you create a structured workout in the workout builder? If you build one, how do you build the FTP test section?

I think they have downloadable workouts in the app and the FTP Test is one of the free be’s

I could be wrong as I don’t use it but I have dipped my toes in it for others on and off in the past.

I haven’t been able to find any kind of downloadable workouts from Tacx other than the public workouts that people do. They say they will be available soon…but I’ve had this trainer well over a year with no update to that…
