Hi @jrocket, thanks for reaching out. As you are the owner of Tobii 5L, this entitles you to a special support channel to deal with any issues or questions you might have. Accordingly, please get in touch with your local sales representative regarding this matter, and they will put you in teach with our specialist integration team.
That being said, the platform is built to support UWP, however there are a number of processes to consider to make it work, so our 5L support team should be able to help you in this regard. Best Wishes.
