Hi all.
I managed to create a fork for the original plugin on github, which has a fix for the HEIC images.

Any HEIC images selected will be automatically converted to JPEG.

To do this, you can replace the module being used with the one that follows attached.

This module includes the change of the Extensibility Configurations to instead point to "https://github.com/noOnePT/cordova-plugin-mediaPicker".

It also includes some quality of life changes to the "GetMedias" client action, like "MaxSelectSize" and "ImagesOnly" input parameters.
