KB4MTO - I have personally used the DJI brand "Mavic/Spark Remote Controller Tablet Holder" that you can order from DJI, Amazon and any authorized DJI dealer outlet. It adjusts to hold just about any tablet, including the 5Se, and is made to fit into the R/C controller's phone slots on the controller for the Mini, Spark, and Mavic series.

You can also use very good mounts by Polar Pro (
