The "Light view" button serves a useful function - when enabled, it will display the fields selected by the user according to the following rule:
Mandatory fields for the linking step.
Filled fields (starting with standard entity fields, then user-defined fields).
Remaining unfilled fields.
Let's take a closer look:
For example, in the integration process, several fields are involved, located at the bottom of the modal window for setting up the linking step.
To avoid searching for the field that we have filled in each time, we will enable the display of the main fields.
Now, when accessing the linking step settings, it is immediately visible which fields are filled, eliminating the need to search for them among numerous other fields.
