How to correctly specify the request in the "Profile fields" in the Bitrix user filter?

Question

1C-Bitrix

The filter has a field called "Profile Fields". how to use it correctly to filter by one of the custom fields?

Answer 1

Just enter the value of the field.
If we talk about custom fields (which are UF_*), then they are filtered by them as by a separate field (add the field to the filter).
In the settings of the custom field itself, also specify the possibility and type of search.
