Tested this out today...I have the Dji mini 2 which uses your phone...I have a Samsung phone which uses smartview which mirrors on a TV, using a dedicated wifi link. So in the backcountry where there is no wifi it will still link, Chrome cast and the like needs a full out internet connection. I have an inexpensive TCL 32 inch tv that weighs like 9lbs and is flat. It is smartview compatible. So I went out today, packed the tv up. Linked the drone, and mirrored my phone to the tv. About a 1 second delay between the phone and tv, but not a big deal. Sure was cool having a 32 inch display for the drone flight. It pixelates a little when moving fast. Cool nonetheless, sitting in a tent flying the drone around with a 32 inch display.
