How to unlock Samsung XCover 4 device

Hi everyone,

I have a problem to unlock/reset Samsung device with Android 9 OS. The problem is that the user has forgotten the password, that he has changed, this device has SMC app version 8.0.**, and no communication with Sophos Mobile Control server. Another problem that my company uses the factory reset deny policy, that works perfectly on Samsung devices.

I tried to enable Baidu service that would help the device communicating with the server, but no luck.

Any advice would be very helpful.
