On my website www.abh-agency.com, I am unable to remove the HTML extension from the other pages of my site, except for the homepage. However, I have requested to remove the HTML extension. As a result, I am unable to index my website on Google.

I have uploaded my website and connected it to my domain name www.abh-agency.com on Godaddy. However, when accessing the site, the URL becomes https://abh-agency-7ad614.appdrag.site/ instead of abh-agency.com. How can I fix this, please?
