How is it possible that getting a tax certificate still requires contacting the company to request it?

Every year it's a hassle to get my tax certificate because they don't bother to provide a way for me to get it on my own. I have to contact them directly to get them to send it to me. I don't understand how a business that has been going for years and for which tax certificates are a standard thing doesn't have any way to get them. The "support" page was written over 10 years ago and refers to something that doesn't exist on the site. There is a "Tax and statement" option in a menu, but all it does is lead to the page with tax registration information. There is nothing about statements or tax certificates.
