Reviews for the venues taken from google

in our APP we are using Hypi, we are getting some venues from google, but we need to be able to leave reviews for those venues in our app (Hotspotz) and to calculate the average, can you please advise how to deal with the issue?

Without further info what I can say is that it sounds like you need to use aggregations https://docs.hypi.app/docs/aggregation/ to calculate the average review
