Logo for social networks

I have to create a logo suitable for the dimensions required by social networks. The logo with the word "Aquadulza" (attached) is the one in full I use for the website. I have to create a second smaller logo to be able to use it on Instagram and other social platforms (round or square shape indeed).
The shape of the Como lake (attached) is the only fundamental element that need to be present. I thought of creating a kind of shield with the lake in the center, but other alternatives are obviously possible. Give free rein to your creativity.

Keep in mind that the brand sells luxury products, so the style must be elegant and refined.
