Drywall mud can be used to skim coat concrete, it’s done fairly regularly in commercial construction.

Also, I don’t know how old your condo is, but it never hurts to test for asbestos.

This is the way..... that I did it once in the past and it worked well for me. I believe I used the Ace branded green cap. Notes are: break-up the work into 1h increments due to arm fatigue. It's a real mess, so prep with plastic, including runners outside of the work area for wet/white bootprints. Wear a hat when removing the wet popcorn.
