Getting JWT token for logged user

In my WordPress website I am hosting a web app made in React and I would like WordPress users to be synced with the app, using WordPress standard authentication (so I don’t actually know my users’ passwords).

If the user is logged in in WordPress, I would like to automatically log in the React app with that specific user.

React is trying to get the JWT token with a POST request to https://mysite.com/wp-json/jwt-auth/v1/token and in the form data is setting custom_auth=1.

I tried this:

function mysite_autologin($custom_auth_error, $username, $password, $custom_auth) {
		$result = $custom_auth_error;
		if (is_user_logged_in()) {
			$result = wp_get_current_user();
		}
		return $result;
	}
	add_filter(	'jwt_auth_do_custom_auth',	'mysite_autologin',	10,	4);

Unfortunately React always gets a 403 error:

{"success":false,"statusCode":403,"code":"jwt_auth_custom_auth_failed","message":"Custom authentication failed.","data":[]}

Is there any way to expose JWT token if the user has already logged in via WordPress authentication?
Many thanks in advance, all the best.
