Is there a more detailed guide on how to use this package? Lacking basic instructions.

Requesting some documentation or assistance on how to use this package. For instance, we're using pxlrbt\FilamentExcel for export, which then gives us an excel file, it would be great if we could just alter data in this file or add rows and use that file for import, but this is where I don't know how to handle columns or anything as it really doesn't say in your readme.usage part - for instance, headers that come from relationship id? ie. customer.name, it's the customer name in the excel file, but how do we tell the import that it's the id of the name etc?

We have booleans represented as yes/no and not 1/null in our export as well, so when we import that, how do we define that as well?

It might be me that's just new to the fundamental parts of import in laravel/filament, so any assistance would be great. Thank you.
