Godaddy masked domain forwarding

Looking to configure masked domain forwarding for some godaddy domains.

Hoping to configure godaddy DNS (or products) to have child1.com.au and child2.com.au domain forward with masking to myapp.com.au/index-child1 and myapp.com.au/index-child2 respectively.

That is: user enters child1.com.au and the site navigates (redirects to) myapp.com.au/index-child1 and displays child1.com.au in the browser’s address bar.

Has anyone managed to do this?

I’ve been going in circles with godaddy support who say it can be done with their hosting products (and use the SSL domain forwarding there) or by using an SSL on each of the child domains. Unfortunately, nobody there could explain how to configure the products they recommended to purchase.

Do we know if bubble.io even supports this concept? I’ve seen discussion on domain forwarding with masking with no real bubble.io solution (have seen and tried 3rd party options like coalias but would prefer not to have an intermediary layer there).

If possible in bubble.io, does anyone know hot to configure godaddy (and what products are needed)?

Thanks in advance.
