low_search Field Grid and a relationship inside a column of the grid

Question

I saw a similar question from 5 years ago, but I stumble upon the same question concerning low_search and combination with grid field and inside a column with a relationshipship.

Does low_search allow for a combination search of the two? I presume it would have syntax like this: search:fieldname_of_grid:child:columnname_in_grid

Does anyone have a lead how to manage a search like this?

The question from 2015: Channel Entries - searching relationship field?

Or do I need to write a custom filter for this?

Looks like it was in the documentation all along: https://gotolow.com/addons/low-search/docs/filters#relationships

The correct filter syntax you can use to search for relationship field inside a grid: child:grid_field_name:column_name_insidegrid
