Unclosed tab. How?

Question

Google Chrome

Could you tell me with an example how to implement a "non-closable tab" in chrome? (for android)
I saw this when surfing sites, the page opened in full screen and did not allow anything to be done (on the phone), including closing, even restarting the browser did not help, tk. the page loaded quickly and this script worked immediately. The only way out was to turn off the Internet and launch the browser, then close the tab (because the script could not load).
