complementing the first answer provided in which the idea is to use the previous IDE to enable both services...
reverting to the previous IDE might not be possible, in that case, you need to
- click gear icon (project settings) and select 'Show "appsscript.json" manifest file in editor'
- then in the appscript.json manifest file add both services as shown below under the EnabledAdvancedServices:
{
"timeZone": "America/Bogota",
"exceptionLogging": "STACKDRIVER",
"runtimeVersion": "V8",
"dependencies": {
"enabledAdvancedServices": [
{
"userSymbol": "AdminDirectory",
"serviceId": "admin",
"version": "directory_v1"
},
{
"userSymbol": "AdminReports",
"serviceId": "admin",
"version": "reports_v1"
}
]
}
}
