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.
