Follow up on sticky logo

Hello,

I've read a few different threads so not sure which approach is best.

I added a logo in Layout > Primary Navigation > Navigation Logo

It displays but tiny

Can you please share with me if this is the correct way for doing this and how to set the size for the Navigation logo that displays in the sticky header?

Sticky header is set to hide on scroll, so scroll back up to see the sticky logo.

Thank you
