Where is the "Embed" button located on Adobe Illustrator?
It should appear in the control panel (under the menu bar, at the top of the window) when you have a selected placed item you can embed.
It also appears in the Properties panel when an embeddable object is selected.
I tried the "properties" and don't see it.
Can you screen shot where it is, for better
understanding? I am using the Illustrator
in the Adobe Cloud - - in case that helps.
It is also in the Quick Actions of the Properties Panel.
