Ionic Capacitor - Screenshot to Gallery (iOS)

I need to be able to have the user take a screenshot on iOS and Android and have that screenshot automatically saved to the users photo gallery. Android works just fine with the following code. iOS also works, however it saves the file in a temporary directory so I need to move the file to whatever directory it needs to go to on iOS so the user can see it in their photo gallery.

import { Screenshot } from '@ionic-native/screenshot/ngx';'jpg', 80).then((res) => {
  this.filePath = res.filePath;

Is there a way to use the FileSystem Capacitor API to save this photo at this this.filePath to the iOS gallery?

Is there another way to go from screenshot to gallery on iOS?

I’m willing to pay in ETH for a solution. I need a solution soon.
