How to fix a broken piece of cement by the garage door

A broken piece of cement at the corner of a garage door creates an open gap that foam and caulk alone may not permanently solve. Homeowners facing this issue need to know whether they can patch it themselves with standard exterior sealants or if the damage requires hiring a masonry contractor.

New home owner here, I noticed this gap at the exterior top right corner of our garage door.source ↗

The other side is flush and caulked but it looks like a piece of cement broke off here on the right.source ↗

Can I fill the gap with foam and then caulk it with OSI Quad Max?source ↗

Or let me know if I need to get a masonry contractor involved instead.source ↗
