Cracks in garage floor via /r/DIY

Cracks in garage floor

I just bought a house that's relatively new (built in 2019) and noticed these cracks in the garage floor. They look like hairline cracks for the most part, but there's one section where the cracks are widest at around 2mm.

There doesn't seem to be any water/leakage, and the cracks do not extend up the garage wall or anything like that.

Can I repair these myself or is it something serious that only a professional should handle?
