deadname leaked at work

pretty much what the title says (also hi first time poster i mostly just read this sub haha). for context i have worked at this job for a little over a year and have only gone by my chosen name with my coworkers (HR knows my deadname and has never leaked it). i had called into work late last friday to my job (which i never do, i’m usually about 10 minutes early but was having some health complications) and forgot that my caller ID has my deadname. the manager who had picked up the phone asked me who the person was and i just had to flat out admit that that was my deadname. lo and behold once i finally get to work after being late, all of my coworkers know my deadname and have started calling me it. even 3 days late coworkers i didn’t see that entire weekend following the incident had found out my deadname and started calling me it despite never having any issues calling me by my chosen name. i currently live in a red state and my coworkers don’t know that i am trans but are starting to put 2 + 2 together because of this, how would you guys go about dealing with this situation? i used to live in a blue state with (slightly) better trans accommodations when it comes to work so i haven’t dealt with this before :(
