findDOMNode is deprecated in StrictMode warning

[josebui]

Describe the bug
Using Strict mode, I am getting this waring message:

      Warning: findDOMNode is deprecated in StrictMode. findDOMNode was passed an instance of Transition which is inside StrictMode. Instead, add a ref directly to the element you want to reference. Learn more about using refs safely here: https://reactjs.org/link/strict-mode-find-node
