Accommodations

Hey y’all, I’ve been trying to figure this out myself but am a little confused ! Does POTS qualify for accommodations through the ADA? And if so, how do we go about getting those accommodations ? I’m asking because I had to miss a “mandatory staff meeting” today due to feeling sick which makes my POTS so bad so I was not comfortable driving. My workplace is not aware that I have POTS so I’m thinking it may be smart to let them know and if I have the right to accommodations that would be helpful to know !
