add new domain when wordpress is hosted on a subdirectory

Hi.

I have successfully installed and activated your plugin and it works fine, thanks.

I have my wordpress installed in a subdirectory: https://mydomainA.com/mysub

I would like to access the site using https://mydomainB.com

I can’t figure out how to do this.

Currently, I am only able to make it work if I use https://mydomainB.com/mysub

Please advise.
