How do I remove the MHA add-in from my outlook client

[doschecks]

I'm using Microsoft® Outlook® for Microsoft 365 MSO (Version 2312 Build 16.0.17126.20132) 32-bit. I had MHA install locally on my outlook client, it has been working just fine. However my company asked me to remove it. I couldn't find it this add-in anywhere from my app list or add-in list. I search the web and tried many possible ways to remove the add-in, but I failed. I have no idea how to remove it since I couldn't find it anywhere other than it's visible on my outlook home ribbon. Please help if you know how to remove this add-in. Thanks!
