Error 403 - link to update new-version-2-22-6

Hello, I have an error 403 with the link for update new-version-2-22-6
joomdonation.com/index.php?option=com_dm...kage&document_id=131
Do you have a correct link?

Hi,
To update extension from Backend side, you should follow below steps:
1. Register a Download ID from: www.joomdonation.com/download-ids.html and enter it in Configuration page
2. Publish the Joomla Installer plugin: OS Services Booking Update package.
After that, you will able to update extension from Backend side.
Thanks

After publishing "OS Services Booking Update package" => update OK

You're welcome, David
