Load Balancer in front of Object storage for custom domain and SSL

In the tutorial "Object Storage - Enabling HTTPS on a static website using a custom domain"

https://help.ovhcloud.com/csm/en-ie-public-cloud-storage-s3-static-website-https?id=kb_article_view&sysparm_article=KB0058080#step-12-configure-a-server-cluster

We need to obtain an IPv4 for the bucket "website" domain.

However, when I look up the the IPv4, I see the static website default URL is a CNAME and not an IPv4. 

host xxx.s3-website.de.io.cloud.ovh.net
xxx.s3-website.de.io.cloud.ovh.net is an alias for s3-website.de.io.cloud.ovh.net.
s3-website.de.io.cloud.ovh.net has address 141.95.67.81

When I then use this 141.95.67.81 in the load balancer as "Server IP", the result is that I am redirected to https://www.ovhcloud.com/en/public-cloud/object-storage/ instead of the content of the bucket being served.

1. Is the tutorial missing important steps? 
2. Do we need the "bare metal load balancer" as a front for an object-storage static-site, as mentioned in this tutorial, or do we need the new "Public Cloud" load balancer instead?
3. Can we obtain the IP address for a bucket itself at all? If not, is it possible at all to have a static site in object storage over SSL on a custom (root) domain?
