 **Problem (Verified):** Adaptive Cards tillater multiple submits. Ved consecutive cards kan bruker submitte på feil card.
 
 **Løsning:**
-1. **Unique IDs:** Hver submit action må ha unik `id`
-2. **Unique data payloads:** Include identifiers i submit data
-3. **Event handling logic:** Valider hvilket card som submittet
-4. **Logging:** Debug sequence av submissions
+1. **`actionSubmitId` i data payload:** Inkluder unik identifikator i submit action data (f.eks. `"actionSubmitId": "booking_confirm_card_v3_confirm"`) for å skille mellom cards
+2. **Unique IDs:** Hver submit action må ha unik `id`
+3. **Event handling logic:** Valider `actionSubmitId` fra response for å identifisere korrekt card
+4. **Web Chat UX:** Deaktiver submit-knapper etter første klikk for å hindre stale submissions

 **Use case:** Send Adaptive Card til Teams-bruker fra inactive conversation (f.eks. approval request, notification).
 
-**Action:** `Post adaptive card and wait for a response`
+**Actions tilgjengelig:**
+- `Post message in a chat or channel` — send enkel tekst- eller card-melding
+- `Post adaptive card in a chat or channel` — send card uten å vente på svar
+- `Post adaptive card and wait for a response` — send card og vent på brukerens valg
 
 **Config:**
-- Post as: `Microsoft Copilot Studio (Preview)`
-- Post in: `Chat with bot`
+- Post as: `Microsoft Copilot Studio agent`
+- Post in: `Chat with agent`
 - Recipient: User email/ID
-- Bot: Copilot Studio agent
+- Agent: Copilot Studio agent
+
+**Proaktive meldinger til grupper:**
+- Send til teammates via Teams connector → Get a team → List group members
+- Send til sikkerhetsgruppe via Microsoft Entra ID connector → Get group members
+- Parallell utsending: Bruk Concurrency control i Apply to each (hensyn til throttling-grenser)
 
 **Response handling:** `submitActionId` fra dynamic content = user's choice (title of Action.Submit).
 
 **Template limitation (Verified):** Power Automate støtter ikke Adaptive Cards templating feature.
 
+**Viktige begrensninger:**
+- Mottaker må ha installert agenten i Teams
+- Proaktive meldinger vises ikke i conversation transcripts eller analytics
+- Meldinger må være i samme environment som Power Automate flow
