Greetings Nicole!
We also have an internal support web messenger (powered by a Virtual Agent) on our intranet. Within the script section of our html code, we added the code you referenced from the messenger plugin resource article. Since then, as soon as our support page loads, our web messenger widget automatically opens.
Is that code working for you?
