How to make a standing coin shaped object round at the contact of the buildplate?
Hi, I printed a standing coin shaped object but when I removed it from the build plate, I noticed that at the contact region between the object and the buildplate, the edge is not round but flat. I chose Support everwhere before I generated the G-code. How do I solve this issue? Will having more support material between the edge of the standing coin shaped object and the buildplate solves this issue? How do I add more support material to raise the rounded object being printed?

A round object will be restricted to steps defined by layer height when standing upright.
There is an option for variable layer height that you can try.
A raft might also help with roundness as the first layer is squished onto raft instead of buildplate.
Pictures would help.

Print the coin partl flat. Rounded undersides are always difficult for FFF printers as there is little support underneath and the severe overhangs literally print in air. You can stick supports underneath those layers, but the need for those supports to be removable requires a small gap, so there will still be some sagging.
You may have to reorient the part in the bed, or even cut it apart and assemble after printing for best results. Save a 3MF project file with your part and settings, zip it and attach it to your response and more suggestions may be forthcoming.
