Currently, OWASP Nest does not track which Slack channels are associated with OWASP entities (Chapters, Projects, Committees).
To improve communication mapping, we should create a model that links OWASP entities to their related Slack conversations.

Describe the solution you'd like

1. Model changes

   • Create a new model (e.g., EntitySlackConversation) with the following fields:

     • entity – Reference to the OWASP entity (object type + object ID using a GenericForeignKey)
     • conversation – ForeignKey to slack.Conversation
     • is_main_channel – Boolean field to indicate if the linked conversation is the main channel for that entity
     • is_reviewed – Boolean field to indicate whether the link has been verified/reviewed

   • Constraints:

     • An entity should not have duplicate links to the same Slack conversation (unique_together on entity + slack_conversation).

2. Data sync changes

   • Create a new management command owasp_match_channels (following the pattern of github_match_users).

   • Functionality:

     • Populate EntitySlackConversation records for Chapters, Committees, and Projects based on available Slack data (it's currently OWASP Slack workspace only).
     • Initially set is_reviewed=False for newly created records.
     • Support bulk approval of channels via Django admin actions.

Are you going to work on implementing this?
