SCUF on PS5 (Remote Play)

Quick how to setup your SCUF or any other controller using Remote play via PS4. The same can be accomplished through the PC application of Remote play.
I did test Remote Play on my Samsung S10 and it will work fine with a DS4 but not a SCUF. Uncertain on other controllers. This does mean if you have purchased the DS4 Back Button Attachment, you can use it.
Sorry for the poor filming LOL
