How do I configure application continuity for ADW-S (Serverless)?

Summary: We are running the Oracle Integration PaaS Service. It connects (via the default ADW wallet) to an ADW-S DBaaS Sevice. When the ADW service is patched (weekly on Sunday's) our Integrations experience intermittent failures. This should not happen as ADW updates should be transparent to the customer. I believe that we need to configure either Application Continuity or Transparent Application Continuity to avoid connection disruptions to the ADW service when planned maintenance activities occur. I've reviewed the documentation below and I wonder which option (AC or TAC) would be appropriate to make the Oracle Integration Service's connection more resilent?
