Some REST API calls return status 405 using PowerShell

I'm testing the waters with some REST calls for Power BI. I'm using the PowerShell cmdlets. I can successfully make calls to some api endpoints for example listing the refresh history of a dataset

Datasets - Get Refresh History In Group - REST API (Power BI Power BI REST APIs) | Microsoft Docs

But others return an error even though I am following the documentation. For example,

Datasets - Cancel Refresh In Group - REST API (Power BI Power BI REST APIs) | Microsoft Docs

Invoke-PowerBIRestMethod -Method Delete -Url 'groups/xxxxx-xxxx-xxxx-xxxx-xxxxxc54c/datasets/xxxxxx-xxx-xxxx-xxxx-xxxxxx2bb0f/refreshes/xxxxxx-xxxx-xxxx-xxxx-xxxxx5b444'

 Message : Response status code does not indicate success: 405 (Method Not Allowed).

 I had similar error trying to invoke
