Override block summary in Mosaic


I am looking for how can I do an override of a block sumary list in mosaic.

I have searched and I read all the documentation about that in https://training.plone.org/5/mastering-plone/zpt_2.html#the-summary-view but it only work in a page view.

I`ve tested the same with this file but it dont work


Just checking, do you have jbot configured?
Your configure.zcml should include something like this:

<include package="z3c.jbot" file="meta.zcml" />

    layer="<layer>" />
