Tub cracked side lip, replace or patch up?

I have a newly installed tub and unfortunately it has a crack down the outer edge or front lip about 1 to 2 inches and it also goes all the way to the edge.

I am afraid of it running and getting bigger, and I am not sure the material if it is acrylic, polyester or fibreglass if that matters?

I am wondering should I replace entire tub or patch it up? Thanks for any advice or knowledge.
