Currently the legend patch functionality is missing completely from the documentation. There are a few open (automatically generated) issues on those, but main documentation is actually completely missing. Could be added as a new topic under Legend items

It looks like this has been addressed somewhere between 3.16 and 3.28 - https://docs.qgis.org/3.28/en/docs/user_manual/print_composer/composer_items/composer_legend.html#customizing-legend-items.

Can it be closed, or is more detail needed on how to use the shape/custom symbols?

Hi @ioalexei Legend patches are also described here. I think this one can be closed, but I would like to have confirmation from @DelazJ.
