Please have a try to add the json code snipped in the ARM template.
"resources": [
{
"apiVersion": "2015-08-01",
"name": "appsettings",
"type": "config",
"dependsOn": [
"[resourceId('Microsoft.Web/Sites/Slots', variables('webSiteName'), 'Staging')]"
],
"properties": {
"AppSettingKey1": "Some staging value",
"AppSettingKey2": "My second staging setting",
"AppSettingKey3": "My third staging setting"
}
}
]
