Galaxy S21 with broken screen, Knox protection - How to input the pin with OTG mouse AFTER restart

[efixs]

Hello
My Galaxy S21 screen has gone black, touch isn’t working either.
I've connected an official samsung OTG HDMI + USB connector and attached a USB mouse.

I can see the screen with the lock icon using the HDMI display on a tv, but since I've restarted the phone, I cant see any mouse cursor (not any external keyboard is working).

I believe it is in this way since Knox is protecting the input of the pin in the startup of the phone and doesn’t allow any external devices.
Anyone has any idea how to enter the pin?

(ADB doesn’t work in this stage also and the phone is not USB debugging enabled).

Help please!

Welcome to AC!
That lock icon should be your pin.

When u connect the phone to computer does it recognize it ? Can you get into download mode ?
