Trying to implement in PageLines

Hi

I’m trying to implement polylang flags in PageLines template. I’d like it to be somewhere at the top of the page ; however, the standard interface doesn’t offer widget in header, and it is proposed in the navbar but doesn’t work. I’ve tried adding the line of code suggested (<?php pll_the_languages(); ?>), but PageLine code is so compact, I couldn’t find where to insert it to make it work properly.
Any suggestions ?

Merci !
