Is Pinnable ChatGPT: pin GPT chats in sidebar safe?

Pinnable ChatGPT accepts auth details from the page URL and renders the supplied email inside the ChatGPT sidebar.

On chatgpt.com, the extension reads a #pinnable_chatgpt_auth URL fragment containing an email, plan, and signature, validates it with a key included in the extension, and saves accepted values in Chrome sync storage. The saved email is then inserted into sidebar license text with innerHTML, so crafted auth data can change what appears in that area.
