Description

When we are facing a multilingual website, it's important to indicate the change language toggle.
We achieved a good result in the desktop version but I think in such a scenario, it's better we follow the desktop version to show the current language beside the icon instead of the English version of toggle only.

In the above image, I prefer to see فارسی instead of Languages
or when its English, I prefer to see English instead of Languages
