Homepage Logo size fix required for mobile/tablet devices

I have a website on Square Online platform not square space - www.crazycovers.co.uk - the logo seems to be too small on smartphone and tablet devices. However, it looks fine on desktop. I need this issue rectified asap.

Square help ask have stated the following:

"For an immediate improvement, you might consider editing the original logo image. The current image has significant whitespace around the actual logo. By reducing this whitespace, you can effectively increase the size of your logo within the existing space, thus making it appear larger on all devices.

You could potentially crop some of this surrounding whitespace or, if feasible, adjust the logo's dimensions to utilise more of the image's area. This will allow the logo to appear bigger within the existing constraints, without impacting the overall layout or compatibility of your website across different devices."
