Invoke an Azure Function from Azure Workbook (Custom End Point datasource)

Hi all,

How to call an Azure Function from an Azure Workbook Table, as a Custom Endpoint datasource. Both resources are in the same resource group.

My Azure Function API :

- Is configured to require  authentification.

- Has CORS activated

- Has System managed Identity activated.

- Has the following roles granted to it from the Workbook IAM  :
   - Contributor
   - Reader
   - Workbook Reader

When I call the API via its direct link (https://FunctionAppResourceID.azurewebsite.net/...) to setup the workbook datasource, I got the error You do not have permission to view this directory or page.

Is their any way to do this properly ?

Thank you in advance for any help.

Regards.
