Lack of Navigation Bar for Documentation on Mobile Devices

Description:
Currently, the Enatega Multivendor and Single Vendor websites lack a navigation bar for accessing documentation on mobile devices. This absence can impede user experience, especially for users who frequently access the site on their mobile devices and need quick access to relevant documentation.

Steps to Reproduce:
Open the Enatega Multivendor or Single Vendor website on a mobile device.
Attempt to navigate to the documentation section.
Observe that there is no dedicated navigation bar or easily accessible link for documentation.

Expected Behavior:
A navigation bar or a clearly visible link/button should be present on the mobile version of the Enatega website, providing users with convenient access to documentation.

Actual Behavior:
There is no navigation bar or prominent link for documentation on the mobile version of the Enatega Multivendor and Single Vendor websites.

No files, tests, or entry points are named. Start by locating the mobile navigation components for the Enatega Multivendor and Single Vendor websites, then reproduce the missing documentation access on a mobile viewport. Done means both mobile versions expose a clearly visible navigation item or link to the documentation section.
