Anyone know what these slots on the side tables are for?

First off I want to say it's awesome being a part of the Blackstone fam! I wake up thinking what the hell can I slap on that beautiful flat top today LOL.

My wife surprised me with a accessories kit which included a mat that covers the end tables on either side of my 28-in griddle.

As I went to put the mat over it, I noticed the end tables have a slot that look intentionally cut.

Does anyone know what these slots are for?

Otherwise I'm just going to cover them with the mats I just got

Appreciate y'all!
