Processing do not see phone

hello everybody
trying to write mobile app
but when connected phone to notebook it doesn’t shows my phone in android selection menu.
Using windows 10 64 and redmi 9 phone
help pls

Did you enable USB debugging on your Android phone?

ok, your suggestion worked up
but now it returns:

logcat: Unexpected EOF!

This means that either the device shut down, logd crashed, or this instance of logcat was unable to read log
messages as quickly as they were being produced.

If you have enabled significant logging, look into using the -G option to increase log buffer sizes.

don’t understand what does it mean, it downloading code for too long and then this message appears
