obsidianでTODO.mdを左のアイコンから開きたい

main.ts

import { App, Plugin, Notice } from 'obsidian';

export default class MySidebarPlugin extends Plugin {
  async onload() {
    this.addRibbonIcon('checkmark', 'Open TODO Page', async () => {
      const file = this.app.vault.getAbstractFileByPath('TODO.md');
      if (file) {
        this.app.workspace.getLeaf().openFile(file);
      } else {
        new Notice('File not found');
      }
    });
  }
}
