How to use the @embroider/core/src/messages.todo function in @embroider/core

protected treeForTestSupport(): Tree | undefined {
    if (this.customizes('treeForTestSupport')) {
      todo(`${this.name} has customized the test support tree`);
    } else if (this.hasStockTree('test-support')) {
      // this one doesn't go through transpile yet because it gets handled as
      // part of the consuming app. For example, imports should be relative to
      // the consuming app, not our own package. That is some of what is lame
      // about app trees and why they will go away once everyone is all MU.
      return new Funnel(this.stockTree('test-support'), {
        destDir: `${appPublicationDir}/tests`,
      });
    }
  }

treeForAddon(): undefined {
    todo(`ember-window-mock's API can't work as a v2 package, so we're leaving the test code in all the time`);
    return undefined;
  }
}

protected addonStylesTree(): Tree | undefined {
    if (this.customizes('treeForAddonStyles')) {
      todo(`${this.name} may have customized the addon style tree`);
    } else if (this.hasStockTree('addon-styles')) {
      return this.addonInstance.compileStyles(this.stockTree('addon-styles'));
    }
  }
