Drupal 8 page manager and panels contextual filters for views_block I'm working with Drupal 8(first project with 8) and trying to build page (via page manager) with taxonomy tid argument.

As a display variant I use panels and inside of panel I put block, generated by views and this views_block have contextual filter. 

I haven't found the way for how to attach my contextual filter to views_block plugin from panel or associate context to anywhere.

From debug session I know what panels have my argument as a context. 
But how to pass it to views_block plugin inside of panel? 

Thank you for any help and information. I'm ready to digg inside of code(and contribute also, if needed) to solve this.
Alternative, you can use Views to pick up the tax term id's



If your node has multiple tax terms, you need to allow multiple values for your contextual filter
