“Create your own plugin” button not appears to be anywhere

Can’t see: “create your own plugin” button on: https://chat.openai.com.
All guides explain that if you don’t see it there, “you don’t have access yet.” OR you need to join some waiting list.
My question is, besides waiting via waiting list, If I have chatGPT Plus account, why don’t I have access to that: “Plugins” button? When can I expect to receive it?
Is there anything I can do to start adding my own plugins?

thank you!
