//Also on the Manifest file I think Im asking the current permissions but Im not sure anymore so posting the related ones here as well

<uses-permission
        android:name="android.permission.READ_MEDIA_IMAGES"
        tools:ignore="SelectedPhotoAccess" />
    <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"/>
