Google Chat does not make it easy to reference chat threads by linking to them. This plugin adds a button to each thread to copy a link to it and also adds a button to quote reply to messages. Select a part of a message and click on the quote reply button to quote that particular part or simply click on quote reply to quote the complete message. Consider donating to keep the extension up and maintained if you enjoy it. https://bit.ly/3p5hD2o
