Is Redux a secure place to store JWT tokens?

I've been teaching myself Redux, wondering how secure it is to store JWT tokens in a state of Redux.

For example, here is a reducer which is responsible for setting and resetting a token.

export default function loginReducer(state = {
    token: "",
}, action) {
switch (action.type) {
    case "SET_TOKEN":
        {
            return {
                ...state,
                token: action.data,
            }
            break;
        }
    //other cases here
    return state
}

Then, you can store a token in a following way.

    handleSubmit(values) {
        //Calling an API to get a token.
    }).then((response) => {
            response.json().then((jsonReponse) => {         
             //This is where the token is stored!
        this.props.dispatch(loginAction.setToken(jsonReponse.token));
            });
        });
    }

The main purpose of using Redux is to organise states in one place, so I thought it would be reasonable to maintain tokens there.

However, I haven't found a good information resource which explains how secure/vulnerable it is to do so.

(I found several posts as to localStorage vs Cookies. Apparently Cookies would be a secure place for storing tokens, as far as I've researched)

Any advice will be appreciated!
