Foam insulation, but I ended up removing this from the doors as it became too humid (like 97% humidity) - https://www.amazon.com/dp/B086YH7B4T?ref=ppx_pop_mob_ap_share

Here’s the link to the ones I bought. They went up in price but $16 is still a great deal. They came with double sided adhesive for the discs, so I used that. Before I stuck them on, I “dry fitted” then using one magnet on the underside and one on the top to temporarily secure it to the bottom, that way I could play with each of the 4 magnets to make sure they didn’t interfere with anything (my primary concern was placing it in a spot that interferes with the little tabs that hold the side covers in place). That way I was able to make sure that the center cover sat correctly and lined up prior to actually securing them with the adhesive…I hope that makes sense.
