Menu Max Width + Centered

Good day, and thanks for the amazing plugin. After using it on mobile for some time, I’ve decided to enable the menu for all devices.

Issue:
My website has a maximum width on desktop and therefore the mobile-menu is much wider than the page’s content.

Attempt:
By targeting the “mob-menu-header-holder” css class I was able to set a maximum width. However, I’m unable to center the menu regardless of what css rule I use. It always floats to the right.

Request:
I need assistant in creating a css rule override that will set a maximum width for the menu while also keeping it centered.
