SNOW VENDOR suggest like "The reason you are seeing over-allocation on ihub starter pack is due to many REST API calls made by "Send personal message" from Microsoft Teams graph spoke, which come under "integration hub starter" subscription entitlement.
From the integration hub usage dashboard, we can see that your ihub tasks are exceeding the allotted licensed value of "100000"; that is why you are seeing the over-allocated remark." so need some more assistance on this like they shared only where is the issue but not find exact issue to fix
