ffmpeg command to convert prores to hevc mp4 with alpha layer that works in safari

Hi, i am struggling with ffmpeg making a video with transparency.

I have output a prores 4444 with alpha .mov and have successfully created a .webm file with transparency that works great on chrome and firefox etc but doesn't work on safari or edge.

I would like to have a reliable ffmpeg command that will convert a prores 4444 with [login to view URL] into an hevc .mp4 or equivalent that will work on safari, iPhones and iPads.

I have an example html file which works in chrome but not in safari that i can send if needed
