Module Position 'header-r'

joomla ver: 5.1.3
template: ja_athena_tpl_1.1.1
t4 system: 2.4.0

Hi, I'm having the difficulty with the module position: 'header-r', it's just not there.
How to add and use it?

Thanks & regards

It's loaded inside the mainnav block of your site:

I just created a custom HTML module with the same content as our demo site and assign to header-r position for you.

Kindly check.

Thanks a lot... its working now
