I'm using google dialogflow to make a whatsapp chatbot. I need to access firestore which contains sensitive data in other collections. Admin sdk is usually used in cloud functions but since it can access any collection in firestore with ease, i wanted to know if it is safe to use it or should i opt for a different option such as firebase client sdk.

Dialogflow is linked to a third party service (QuickWork) which links my bot to Gupshup to use the whatsapp business api.
