How to log out using firebase REST API?

Question

RESTful API

Good afternoon. I am doing a simple user authentication using the Firebase REST API following this guide:
https://firebase.google.com/docs/reference/rest/auth
Sign In:

await fetch(
            'https://identitytoolkit.googleapis.com/v1/accounts:signInWithPassword?key=AIzaSyAgTJyexl3AhXyoRfnB6LSyv0ZBoaP3Nm8',
            {
                method: 'POST',
                headers: {
                    'Content-Type': 'application/json',
                },
                body: JSON.stringify({
                    email: values.username,
                    password: values.password,
                    returnSecureToken: true,
                }),
            },
        )
            .then((response) => response.json())
            .then((response) => console.log(response));

and sign up:

await fetch(
            'https://identitytoolkit.googleapis.com/v1/accounts:signUp?key=AIzaSyAgTJyexl3AhXyoRfnB6LSyv0ZBoaP3Nm8',
            {
                method: 'POST',
                headers: {
                    'Content-Type': 'application/json',
                },
                body: JSON.stringify({
                    email: values.username,
                    password: values.password,
                    returnSecureToken: true,
                }),
            },
        )
            .then((response) => response.json())
            .then((response) => console.log(response));

go with a bang, the user registers, appears in the system, but remains logged in forever ...
The manual does not contain a clause about LOG OUT. Googling didn't help unfortunately.
This is a simple form through email and password. Can anyone come across? To understand At least what endpoint the request should have and what to send there?

Answer 1

curl 'https://identitytoolkit.googleapis.com/v1/accounts:update?key=[API_KEY]' \
-H 'Content-Type: application/json' \
--data-binary '{"idToken":"[FIREBASE_ID_TOKEN]","deleteProvider":["[facebook.com]"]}'

Documentation
In general, I use firebase in React via npm and I advise you.
Then it would work like this: firebase.auth().signOut()
