Just tape it in place as best you can and prop it up into place if needed. Then leave it be. I’ve seen them come back from dam near 99% snapped off. If it stays green and is still alive in a few days your good to go, just leave it be and don’t try and lst that branch anymore for a bit untill it can heal itself, it will make like a knuckle around it when it is healed. if not it will just wilt away and dry up in a day or 2. Your plant should be fine either way. It will either repair the break or seal the branch off and continue growing other shouts. Cheers!💨
