How to I remove elements from symbol? I want to make changes to only one page with the symbol

[goose (Melanie)]

Hi, I just made a symbol with a bunch of elements. I want to make changes to only one page with the symbol, but if I made a change in the symbol - every page changes. How can I remove the symbol from my elements in just one page?

Yes when you click on the symbol there is an option to unlink the symbol ( dropdown) : unlink instance
