This isn't proper ARM syntax. Here is an example of Authsettings: https://learn.microsoft.com/en-us/azure/templates/microsoft.web/2022-09-01/sites/config-authsettings?pivots=deployment-language-arm-template and Authsettings v2: https://learn.microsoft.com/en-us/azure/templates/microsoft.web/2022-09-01/sites/config-authsettingsv2?pivots=deployment-language-arm-template
