How to delete a photo in Ayala app?

here's Ayala dating app and how to delete a photo here I'm just curious like so I have one photo I can replace it and then I can just type here okay and that's okay that's how I delete the photo because this app makes it a bit difficult if I add a new one I don't know how to delete one main photo so if you just have one left one photo remain it's not possible to delete it anymore so you need to replace it with other photo uh and then just replace it to some other photos that's how you delete it
