I don’t think there is much you can do when the lighting is that bright.
I gave it a shot anyway and here’s what I got. Played around with the editing features.
I’m not great with editing so I can’t tell you a whole lot on what to do to help with that. Maybe @azurbanclucker can help.
How would I convert it with just the IPhone editing app? Are you able to give it a shot for me please, because I don’t believe I have the editing materials for it….TIA
