Not able to create new tour tip plugin

Dont know if its a bug or I am doing wrong. I am just trying to create a new tour tip, so I have write this :-

id: rohit-custom-2
module: rohit_tour
label: Custom Tour
langcode: en
routes:
  - route_name: node.add_page
tips:
  custom_1:
    id: custom_1
    plugin: text
    youtube_id: 'momomo'
    label: Custom tour for learning
    body: <p>dsdfdsfds</p>
    weight: "1"
  block-seven-content:
    id: block-seven-content
    plugin: custom
    my_id: 'momomo'
    label: Custom tour for learning
    attributes:
      data-id: block-seven-content
    weight: "2"

in modulename/config/install/tour.tour.rohit-custom-2.yml file
Then I created a class in src/Plugin/tour/tip/TipPluginCustom.php as below.

     /**
 * Displays some text as a tip.
 *
 * @Tip(
 *   id = "custom",
 *   title = @Translation("CUstom")
 * )
 */
class TipPluginCustom extends TipPluginBase {
  protected $my_id;

  /**
   * {@inheritdoc}
   */
  public function getOutput() {
    $output = 'My Custom tip id => ' . $this->my_id;
    return array('#markup' => $output);
  }

}
  

where custom is my tip id.

But only first tour is showing.

Am i missing something ?
