Export content credentials with UXP
Currently when exporting from UXP content credentials (C2PA data) are not exported in the file no matter how the user has content credentials configured. In the native export screen there is a checkbox to attach or embed the content credentials - could this be exposed to UXP to allow a flag to be passed using this check when calling the await activeDocument.saveAs.png(aFile, true/false) or the batchplay equivalent of
_obj: "save",
as: {
_obj: "PNGFormat"
Failing that, the behaviour should be that that if the user has enabled content credentials on the file, then the export from UXP should automatically add these to the file
