Does not work in Vivaldi

[j-xella]

I followed the instructions, the extension got installed. I can see buttons at the bottom of the chat. However, none of the buttons seems to be working - all they do is to create some weird selection around the chat name on the left side of the page.

When I go into extensions -> ChatGPT Download -> Errors, I see this:

Error:

Uncaught TypeError: Cannot read properties of null (reading 'style')
Context
