Hello there,
we hope you’re doing well!
Have you tried opening a support ticket? In case you want to add carriers, you must request it through a ticket and we will help you.
It should be noted that what we have mentioned we clarify in this section of our documentation.
Let us know any news, please.
Have a nice day!
I did opening support ticket and problem solved. But I suggest that Plugin (Pro version) should have custom carrier. So users can add whatever carriers. Thank you for your listening! We are waiting for next update( of Pro version) with that function.
Regards,
