Hi @HomeDIY18,

You could go a couple of ways with this — you could either apply grout into that gap to match the tiled surface, or you could use a white silicone sealant instead. Silicone would be a good option because it would fill the gap and also seal the porosity of the exposed tile adhesive, helping to prevent any moisture getting in.

Here's a helpful guide: How to apply silicone sealant.

Please let me know if you have any questions.
