Change to standard version

hello
When i change my iphone to standard version, how i comeback to recognize mobile pro?

MJ installs "Select Markup" module in "footer" position of desktop website. If your desktop template has no "footer" position, change position name in module settings to one existing in the template. Then users can switch back to mobile version using link in this module.

thanks, where i find that module?
i try in joomla but i didnt see

In Extansions->Module Manager, there are 2 instances of the module titled "Select Markup".
