So, are you not viewing this option while in a prototype?

Correct, I used to have that option, not anymore
Might be a permissions thing, not sure if you're the owner of the file.
Anyway, you can try this to check:
- Copy the link of the prototype
- Paste it on a browser tab
- Change this piece in the link
- proto → design

Access it and check if you have permissions to view it.
Thank you giliard! Your solution took me to a request access page.
It seems the owner didn’t actually grant me the access or there’s some other issue on his side, hope this works.
Bless you for your time & knowledge!
You're welcome! Glad I could help.
