Need to remove Shopify Dawn them header white space

Hello, can someone help me to fix my websites homepage header? When I added the logo it created broad space both in the top & bottom of the header. I tried adding this code but it just reduced the little bit of extra space from bottom but it totally disappeared my logo.

@media screen and (min-width: 800px) {
.header__heading-logo {
max-height: 100px !important; (I just changed the 100px to 0)
object-fit: cover !important;
width: 100% !important;
width: 300px !important;
max-width: 100% !important;
}

Now I’m unable to fix it.

I also added few codes in header.liquid for transparent header option which left a code scrip on top of the header. How to remove it?

Here is the website URL: https://52e6b5-83.myshopify.com/

its password protected. will share on private msg.

I managed to delete the script reflecting on header but still a broad header.
