Hello - currently integrations in MBI can only be deleted by the support team. I recommend opening up a support ticket and requesting that they delete the integration.
Keep in mind that deleting an integration will also delete any dependent assets, including calculated columns, metrics, and reports. Once an integration is removed, these assets will be permanently lost.
Best,
Chris
