Seam separation granite countertop

Hello!

I’ve got a granite counter where there is moisture getting in to the seam between the contact point of where different slabs were joined.

I’m a little overwhelmed with various products out there and what would be suitable. A clear epoxy or resin? Something that matches color? To be sure, it’s not a crack, it’s just where two surfaces were joined and whatever protection was added when installed by a previous owner is gone.

Thanks for any suggestions- what would you use?

cheers!
