## Questions

### How do you add Googlegemini to a Duaer digital organization?

Open the node panel on the Duaer canvas, search for Googlegemini, and drop it onto the digital organization. Connect it after a trigger or a previous node. If auth is required, save the credential first and select it on the node.

### What should you check first when Googlegemini fails in Duaer?

Read the error text on that node’s output, then confirm the credential still works and required parameters are filled. For app nodes, also check permissions and quota on the provider side.
