Template Challenge Filter


i am working on the your Lightship ARDK for 1 month
and the template challenge sound very good to me
I had a question : i think making some AR filter can be fun, but LensList provide only Social Media filter (Snapshat, instagram, tiktok)
Do LensList provide AR filter for unity ? (i dont find any on the net)
if they dont can i use the unity AR solution and be eligible for the challenge template (Example : Unity3d AR Foundation - Adding Face Masks with AR Face Tracking And Turning Face Tracking On and Off - YouTube) or the OpenCV solution : AR Face Effects for Unity3D asset store augmented reality tutorial - YouTube
Thank you
