Edit multiple frames tool not found

Hello everyone,

I've been making a small animation and now that I have the general motion down, want to make a copy from it and move it somewhere else on the page. I can't find the edit multiple frames button anywhere, is it just gone in the 2021 version or am I overlooking it?

I also tried importing it to the 2020 version, but I can't change my vector object at all or even select the object I'm working with.

Any help will be very appreciated.
