Keeping personal and work contacts separate on iPhone SE

Hello! I use the Zoom phone app on my personal iPhone SE as my work phone. I have not found a way to add work contacts without them syncing to my iPhone contact list. I would like to keep my work contacts and personal contacts separate. Is there a way to do this?

When I try adding contacts to to my Zoom desktop account, they do not sync to the phone app. I just want to be able to see who is calling me, while keeping a wall between my work and personal contacts. Thanks in advance for any help with this.
