It sounds like you're on the right track, but the On-Select Flow (Instant Flow) is not appearing under the Flow > Run menu in your Case entity. Here are some possible reasons and troubleshooting steps:
1. Check the Flow Trigger Configuration
- The correct trigger for instant flows in Dataverse should be: "When a row is selected (Dataverse)"(Not "When a record is selected")
- Ensure that you selected the correct table (Cases) when configuring the trigger.
2. Ensure the Flow is Added to the Model-Driven App
- Navigate to your Model-Driven App
- Go to App Designer > Entities > Cases
- Ensure that Power Automate (Flows) is enabled for the entity.
3. Confirm the Flow is Shared Correctly
Even though you're a co-owner, check:
- The Flow must be shared with your security role.
- Go to Power Automate > My Flows > Select the Flow > Share
- Make sure your user and team have access.
4. Check Environment Connection
Sometimes, a missing environment connection can cause this issue:
- Open Power Automate
- Check the flow and ensure it's connected to the correct Dataverse environment.
5. Verify Solution Context (If Inside a Solution)
- If you created the flow inside a managed solution, it might not show up.
- Try creating a new flow outside a solution.
6. Refresh the Power Apps Interface
- Sometimes, changes take time to reflect.
- Log out and back in, or clear browser cache.
7. Test in a Different Browser / Incognito Mode
- If it's a UI rendering issue, try accessing Power Apps in another browser.
8. Check Microsoft Known Issues
Some users have reported that Instant Flows don’t always appear immediately.
Check Power Automate’s known issues page.
Final Alternative: Manually Add the Flow to Your Case Entity
If none of the above work:
- Go to your Model-Driven App
- Select Cases
- Click Add Command > Automate > Instant Flow
- Manually link your instant flow to the command.
