Unable to change Logo in Highend

Hi — I purchased Highend Plus through Lemon Squeezy and installed the theme successfully. However, the package I downloaded does not contain the expected plugins/ folder or the highend-core.zip file. As a result, I’m missing the Highend Options panel, the logo upload feature, and header customization.

Can you please provide me with the full package that includes all bundled plugins, or direct access to highend-core.zip and any other companion plugins needed?

I can provide my license key or proof of purchase if needed.
