So, I want to create a bot/incoming webhook that would read all the messages in a group and copy it to a spreadsheet. The thing I'm asking here is, can bots or incoming webhooks read the whole group message? In the google chat api page, in the REST api reference bit, link( https://developers.google.com/hangouts/chat/reference/rest/v1/spaces.messages/get ) there is something called >spaces.messages.get but does this get all the message in a group, if so how?
