Yeah pretty much, crack them between whichever teeth you find easiest, then use your tongue, teeth or fingers to split it open then pop out the seed.

You don’t want to chomp on the seed laid flat, you want to split it down the narrow side, i.e. bite on it lightly while it’s upright.

I usually just lightly crack it between my teeth then pinch it between my forefinger and thumb to split it fully.

Yes I usually drop the husk into a bowl or whatever. It’s not wet unless you’re particularly slobbery.
