Get an overview of used features (Jira Cloud)
While there is currently no built in way for our app to get an usage report of the features you can search for created chats/conversations/meetings/emails using the Jira Query Language (JQL).
Here you can filter for a project or other specified filters and add the desired feature lookup:

Here are the different JQL commands you can use for the relevant features:
Chats:
hasChats = "true"
Teams conversation:
hasConversations = "true"
Meetings:
hasMeetings = "true"
Emails:
hasMails = "true"
