Adding own HTML for external webpage in ESM

Hi,

Can you give an example how to include an external link?

We would like to add an extra button besides IT Helpdesk, HR Helpdesk that redirects to a specific Webapplication to report specific issues.

This is what I read in the explanation :

The ESM portal's layout and theme can be customized. External links to an organization's resource page or an intranet page can be added into the portal as well.

To customize,

Click Customize the Portal under Customize the ESM Portal section.
On the Customization page, you will have template variables to render various elements to the layout.
Click the required variable to add to the code. iYou can type in your own HTML code for adding external links for intranet pages or resource pages.
You can preview the output by toggling the Preview mode.
If you want to undo the changes made in the code editor and revert the default layout, click the Replace button placed at the top right.
Use Replace with default content to revert to the default layout. Use Replace with Published content to get the published version of the layout back.
After you have made all the changes, click Save as Draft to save the changes locally and not publish it to the users.
Click Save and Publish to save and publish the updated portal content to all users.
