Reference documentation and code samples for the Google Chat V1 API module Google::Apps::Card::V1::OpenLink::OpenAs.
When an OnClick action opens a link, then the client can either open it
as a full-size window (if that's the frame used by the client), or an
overlay (such as a pop-up). The implementation depends on the client
platform capabilities, and the value selected might be ignored if the
client doesn't support it. FULL_SIZE is supported by all clients.
