building a list in “actions on google”
问题 I'm doing a project where the Google Assistant generates a list of cards about information on research articles. Each card on the list would have the title and URL to the research article. The Google Assistant would ask what subject you wants to research about and the user would reply with the subject matter in one or two words. I have the following questions I understand that the app.buildList() command requires an alias and key variable. Could I level them as blank or null in my code
