How to pass any anonymous function to ref and use that in other react component?

Question

I have 3 functional components and I'd like to pass & manipulate data through useRef.
I am adding this onClose method to current property in one of my component.

const onClose = () => {
    setButtonColor(buttonColor);
};

ref.current = {
    clearSwitchStateOnClose: onClose,  
};

I am calling that method in another component.

ref.current.clearSwitchStateOnClose();

I am receiving this error,

Uncaught TypeError: ref.current.clearSwitchStateOnClose is not a function

Answer 1

I was calling this method ref.current.clearSwitchStateOnClose(); but with that I was also mutating ref. I guess that was causing the issue.
It was something like this,

ref.current = {
    showModal: false,
    modalResponse: null,
};
ref.current.clearSwitchStateOnClose();

After doing this, it is working fine.

ref.current.clearSwitchStateOnClose();
ref.current = {
    showModal: false,
    modalResponse: null,
};

Sorry for not sharing the entire scenario of this situation.
