Inspector Panel (missing?)

Hi there - I’m new to Principle, I am learning with chat GPT. I am trying to locate the “inspector panel” which I’m being told is to the right of the panel, where I’ll have access to opacity, and other options. I don’t see that. I’m being told that I can turn it on with some commands like command shift I, or view>inspector panel or something like that. I don’t have an inspector panel option in the menu bar, and the shortcut doesn’t work.
I am trying to locate the inspector panel so I can get rid of the wonky transition for my bird walking animation, and I want to turn off quick animate. Is there even an inspector panel?

Thank you!
