The connector can assist you as a workplace user to send a comment to Jira directly from Workplace's Jira issue group conversation. 

Sending comments to Jira

• You can send a comment to Jira by mentioning the bot name regardless of whether you are an existing Jira user. The format will be similar to @Bot-name comment “Message”.
  For example:
  A user can mention the bot @Developers with a message in quotes: @Developers comment "Agreed with Rodrigo"

• The add-on user in Jira will be the one that is adding the comment in Jira.

• The comment will have a prefix to mention who added the message and the author of the message:

User pushed this comment from Workplace: “Agreed with Rodrigo”
