After installing Glide Virtual Agent to our instance I do not see "Messaging Apps Integration" under Virtual agent.

Trying to use Messaging integrations with Slack, Microsoft Teams, and Workplace by Facebook.

Missing plugin (com.snc.bot_install_ui )

Check if instance has any of the 2 plugins installed:

IT Fundamentals Dashboard (com.sn_apphealth)
Knowledge PA Scoped App (com.snc.pa.knowledge)

If so, please open a Hi ticket and reference PRB1404597.
