Sliding barn door to add privacy for office space with arched door?

My home office has an open, arched doorway leading to living room. Wanting to add some privacy for calls, etc. but doesn’t need to be fully sound proof. Would you add a sliding barn door on this inside (office side) here, which when open would slide in place of the painting, plant, and record player? There's probably 3-4 inches of space from the left edge of the opening to the adjoining wall so I believe there's space to close.

If barn door (or other), I'd greatly appreciate any suggestions on where to buy. Thanks!
