Phoca Cart & Yootheme don't work for me

[ScaleBXL]

Joomla 5.3.4
Phoca cart 5.2.1
Yootheme 4.5.28

Hello

I have installed the Phocacart_Yootheme_offcanvas_override v4.09, the subtemplate yootheme_phocacart_main, selected the this one in the advanced parameters of Yootheme but nothing !!!

When I try to create a template in Yootheme I haven't any dynamic field of Phoca cart. I haven't any Phoca cart option in Yootheme. I'm a customer of Yootheme so for me it is not to be used with Joomla 5

Any idea? Or a little more complete documentation ?
