Where has the 'Add Collection to Site' button gone?

I am using Microsoft Edge and found that the Add Collection to Site button is not there! Is it to do with the browser I am using? Is there another way to do it?

Thanks!

Hey Olivia,
Did you enabled the developer tools? if you did what button exactly do you refer to?

After creating a collection, the “ad collection to site” button which usually appears right under the collection image is nowhere to be found
