Pointing multiple domains to the same website

I have 3 domains which I want to point to the same url address:
mydomain.org should be the primary domain
mydomain.co & mydomain.com should redirect the user to mydomain.org

I’ve tried to point all the domains to the same server IPs:
and also created C-NAME record for each, pointing to proxy-ssl.webflow.com, but it’s not working.

Thank you for your help,

You should be able to do this with domain forwarding in your registrar settings. I know go daddy has a specific setting for this.

Thank you @DFink, I reached out to the domain registrer and they made the necessary redirect.
