The reference you found is about roll buttons. With a roll button you can send to chat, but cannot activate sheet workers.
With an Action button, you can activate sheet workers, but you cannot send to chat.
These are fundamental limitations of the two button types, and you cannot bypass them.
The API is something different, and can do both of those, but requires a Pro subscription for the campaign's GM.
The reason people are mentioning your current status is because you look like a free user, and from time to time, free users dont realise they need Pro to use Custom Sheets or the API, so they are trying to help you out by letting you know this.

Does the name attribute at least still exist? So I could access the roll with a macro?
I'm not sure what you're asking for here.
