Button besides burger menu in the top menu bar

In the middle of the top menu bar on the mobile view, I’d like to place a “<=” button.
This button should have a simple “javascript:history.back()” link so that the user can go back to the previous page.

This is useful when the website is installed as a webapp and there is no browser around it.

Could you please help me? I’ve seen some requests in the forum for a secondary menu in addition to the hamburger menu, but the PHP + CSS code mentioned seems quite complex for what I want to do.

here what I’d like to achieve…

Thanks in advance!
Bye,
A.-
