How can I redirect "www" to "non-www" when using Google Cloud Storage Bucket

Is there any way to redirect "www.example.com" to "example.com" when using Google Cloud Storage binded to example.com url.

Couldn't figure it out via Domain provider. Already tried adding CNAME to "www.example.com" for redirecting to "example.com"

Or should I open new bucket for www.example.com for all same content?
