How can I make fields default to available rather than being automatically selected?

I'm not sure how to handle it on the tap side (haven't adjusted that before), but when running with Meltano, you can use the

select

plugin config to handle selection in a really nice way, which makes the tap defaults a little less of an issue for consumers. https://meltano.com/docs/command-line-interface.html#select

Thanks for the response @stephen_bailey. I think I figured out what was going on here. The API request was returning all fields, until I figured out how to filter them out based on the inclusion metadata. This was related to the API's implementation and nothing to do with meltano necessarily.
