Open a modal from Nav componant

I have created a modal that contains a contact form.

I want this modal to open when a button is clicked in the Nav bar

The Nav bar currently sits in a component called Navigation.

I can’t seem to get the button to trigger the Modal to open

Currently, the Modal is hidden.
The interaction is set to onClick > show/hide Flex the Modal
