How do we set up kiosk mode in samsung tablet?

I have samsung tablet tab 8, with android 9 installed.

I have trouble to make this tablet as kiosk app, I want to use it for opening my web page,

so everytime the tablet starts it directly open my web page only ( with wifi settings enabled )

I searched around and found Samsung KNOX, but I think it is a paid service, and I have trouble where to download it.

Is there another solution availible?
