Hide annoying App bar in App Mode

[grandsilence]

Hi. Is any solution to hide App Bar in App Mode? very annoying. It appears and disappears when you switch between different pages. This bar does not appear on the main page of the application. App mode is the only convenient way to use sites as apps, in a separate window.
Thank you.

Thank you so much for the solution 

To summarize the solution — you need to change the path in the shortcut.

From

chrome_proxy.exe  --app-id=ilmgmogedobmcfegdjcibiiaodmdenpf

To

chrome_proxy.exe  --app=https://yourapp.com/yourpath

Still, it wouldn't hurt to have a solution to hide this bar.
