I was a tech support in Accenture, and what I do is trouble shoot application issues mostly citrix, Okta, Java, and Global Protect.
I also know how to use Bomgar- which we use on helping our clients solved the issues they are facing.
I was a chat support handling 3 chats at a time.
These could not be enough experienced to what you were looking for but I am willing to undergo some training, I am a fast learner and I can easily adapt to people.
