Sliding door handle gap - not pulling flush to body

[meza]

My sliding door handle never returns flush to the body and is a bit loose. Leaves an unsightly gap. It opens the door fine.

Any way to fix or tighten this gap up?

Also bonus points for how to get hold of the missing lock trim part without paying £20 for a full handle set off Amazon!

I might have the trim piece kicking around in my shed - if I find it I’m happy to send it to you.

Very kind, sir! I’ll send you a PM.
