Chromecast screen Mirroring Is active

This to me looks like either Chromecast or Screen Mirror (screen share).

Hi.

Thank you for your answer. What does it exactly mean?  Chromecaste mirroring screen is active? Does someone can see my phone screen?

@Members_me9cxSk: If you swipe from the top of the screen to the bottom to access your drop down notification menu, can you see any screen mirroring notifications. Typically it should only be possible to screen mirror to a TV after granting permission on both devices, but if you're concerned then I recommend disabling Wi-Fi and restarting your phone.

Czy jest możliwe, że ktoś bez mojej wiedzy połączył mój telefon ze swoim telewizorem aby włączyć Chromecast mirror screen?
