Fix for the following warning: "Notice: Function register_rest_route was called incorrectly...."

Hi, I noticed that when I install and access the plugin, it shows the following warning:

Notice: Function register_rest_route was called incorrectly. The REST API route definition for simple-jwt-authentication/v1/token is missing the required permission_callback argument. For REST API routes that are intended to be public, use __return_true as the permission callback. Please see Debugging in WordPress for more information. (This message was added in version 5.5.0.) in C:\wamp\www\woo2\wp-includes\functions.php on line 5865

I have also figured out the solution for this. The solution is to add 'permission_callback' => '__return_true', argument. Following is the complete solution to be implemented in the following file: wp-content/plugins/simple-jwt-authentication-master/includes/class-simple-jwt-authentication-rest.php

/**
     * Add the endpoints to the API
     */
    public function add_api_routes() {
        register_rest_route(
            $this->namespace,
            'token',
            array(
                'methods'  => 'POST',
                'callback' => array( $this, 'generate_token' ),
                'permission_callback' => '__return_true',
            )
        );

        register_rest_route(
            $this->namespace,
            'token/validate',
            array(
                'methods'  => 'POST',
                'callback' => array( $this, 'validate_token' ),
                'permission_callback' => '__return_true',
            )
        );

        register_rest_route(
            $this->namespace,
            'token/refresh',
            array(
                'methods'  => 'POST',
                'callback' => array( $this, 'refresh_token' ),
                'permission_callback' => '__return_true',
            )
        );

        register_rest_route(
            $this->namespace,
            'token/revoke',
            array(
                'methods'  => 'POST',
                'callback' => array( $this, 'revoke_token' ),
                'permission_callback' => '__return_true',
            )
        );

        register_rest_route(
            $this->namespace,
            'token/resetpassword',
            array(
                'methods'  => 'POST',
                'callback' => array( $this, 'reset_password' ),
                'permission_callback' => '__return_true',
            )
        );
    }

I hope you will be able to add the above fix in your next update.

Thank you.
