Show the Legacy Omnistudio UI

If using Omnistudio's legacy Angular UI is necessary to your implementation, turn on the ShowLegacyOmniStudioUi setting. All new implementations should be done using Omnistudio's LWC designers for future support. However, in rare cases, it may be necessary to turn on the legacy designers.

1. From Setup, enter Omni Interaction Configuration in the Quick Find box, then select Omni Interaction Configuration.
2. Click ShowLegacyOmniStudioUi.
3. Click Edit.
4. For Value, enter true.
5. Click Save.
