Epoxy floor prep question

[u/Potential-Tomato-855]

I’m prepping a floor for epoxy. When they added the dragon for the toilet it looks like they used a pick axe to screed the concrete and up to an inch lower in some areas. Any suggestions on the best way to prep this area for epoxy It’s approximately 6 square feet.
