Grant accessibility permission to a third-party app

Hello, i need to give a third party app the accessibility permission with Scan2Deploy.
The app is a rmeote control app (Supremo) that now, without this permission can only share the screen, with the accessibility permission can also enable the remote control.

Already try the following command via Sca2Deploy script

pm grant it.nanosystems.supremo.addon android.permission.WRITE_SECURE_SETTINGS
OR
appops set --uid it.nanosystems.supremo.addon WRITE_SECURE_SETTINGS allow

settings put secure enabled_accessibility_services it.nanosystems.supremo.addon/it.nanosystems.supremo.addon.SupremoAccessibilityService

But every command fail.

Thank for the support
