addResourceFileToGroup Is not being set for a target UUID that is different than the application native target

Summary

I am trying to use IOSConfig.XcodeUtils.addResourceFileToGroup to add a font to my widget. I expect the second checkbox to be selected after I run prebuild.

Code I am running:

    console.log(`Target UUID: ${targetUuid}`)

    for (const filePath of fontFiles) {
        console.log(`Adding resource file ${filePath}`)
        config.modResults = IOSConfig.XcodeUtils.addResourceFileToGroup({
            filepath: path.join('Fonts', filePath),
            groupName: 'Resources',
            project,
            isBuildFile: true,
            verbose: true,
            targetUuid, // I checked this UUID value and it is correct
        });
    }
    console.log('Resource files copied successfully.')

output of prebuild

The script looks like it runs fine, however, the target exponativefontsexampleWidgetExtension is not selected when I open the workspace.

Thanks! I'm happy to provide more details if needed!###
