i mean you can use that but once a crack happens like, its usually cracked all the way through and probably will grow

If you are somewhat handy its not hard to replace an undermount sink. If you have someone to hold the sink up while the other attaches it to the countertop its pretty easy.

You can absolutely use a silicon permanent sealant if you don’t want to replace it. The same thing happened to my sink. Dry it thoroughly, then apply the clear adhesive along the crack line. Most important, get under the sink and seal the crack line on the underside too. Add a second coat to both sides if needed. I’m going on 8 years with no leaking or worsening with my repair. Good luck!

I would definitely be returning the sink to wherever you got it from
