Debugging mobile websites

Hello, I need to debug a website that is not working correctly on mobile. I want to load it on my eos phone and debug it on my laptop. It is pretty easy on windows+ android, but on eos + ubuntu I am having hard times.

I have followed all the instructions reported here Remote debug Android devices  |  Chrome DevTools  |  Chrome for Developers, until point 7 where my phone is not appearing. Actually I do not receive any dialogue on my latptop when I plug in the phone.

Any ideas?
