Topic subscription limited on toaster?

Question

JavaScript

Hello!
Is there a limit on the number of subscriptions to topics on the toaster?
I subscribed to the topic, they gave a link to Habr, like, to an article about feedback forms, their verification, etc.
In the comments, someone else exclaimed that they say this is it, even the check is ready already.
Maybe someone will suggest this topic or article. All clambered, I can not find that topic, and it is not in the subscriptions.
In general, you need to attach a form to the landing page, "order a call back".
And I don’t rummage in them at all ... I definitely can’t do it myself. I think it will connect.
Thank you!
