Wall solar light (Masonry drill bit size?)

Hello Ring! I had a question regarding the ring wall solar light (https://ring.com/products/wall-light-solar) Can you tell me what size masonry drill bit is needed for this product? I am planning on installing the light in the “mortar” of my brick wall. Being that the light is not heavy, I think installing it in the mortar (instead of brick itself) would work. However, it did not come with a masonry bit and I’m not sure what size is needed. Also, would a regular power drill be sufficient to drill the pilot hole into mortar or is an impact driver needed? Note* I’m not drilling into the brick itself thus I don’t have a “hammer” drill. Thanks!
