I think you’re snookered if you’ve broken the pivot rather that the handle.
If its the handle than have a look here.

There’s no way I could access the latch assembly itself without destroying the glove box front.
it’s easy enough to get the whole assembly out but that’s about it.
I managed to glue it and that worked for a while, but my last attempt involved using a self tapping screw and that’s been in place for quite a while.
Its not pretty, but due to the positioning of the catch you can’t really see it unless you’re on your back in the footwell.
If you are then I’m guessing you don’t care about seeing the door latch
If you do replace the assembly I’d be interested in how much it costs and how easy it was to get the part.
