Help with iOS remote desktop tools

Hello.
Not sure if this is the right room, so please move if in the wrong place.
I recently switched to a desktop PC, and I'm using NVDA Remote and Jump Desktop to control from my phone.
I'm able to connect through NVDA Remote and Jump Desktop no problem, but I don't have an insert key.
Pressing insert on the numpad always sends a 0 even if number lock is off, and the insert on my 6 pack in the middle of the board is treated like it doesn't exist.
I've tried changing my NVDA key to Caps Lock, but iOS intercepts it.
For those of you that use your iOS devices to control a PC, how do you approach this? Any way to get an NVDA key?
Thanks.
