Custom UI for handling interrupts

[beepsoft]

I created an issue for this, but maybe it worth asking it here.

I am evaluating https://github.com/langchain-ai/langgraphjs-gen-ui-examples

I can see in the email-agent example, that the backend interrupts the graph using interrupt() and in response the UI (agent-chat-ui) displays a builtin UI (agent-inbox) for the user to accept, ignore, etc. to stop or resume the graph.

I can also see in the trip-planner example how to push a custom UI to agent-chat-ui when executing a node using ui.push()

Now, is it possible to make an interrupt and display a custom UI for the user to decide instead of the default agent-inbox mechanism? I tried to call naivly ui.push() before interrupt() but then nothing appeared in the UI.
