Postman Flow has no option button on the right toolbar

The postman flow has no option button on the right. I used it couple of weeks ago to add JSON values to the Start block.

Where is it? screenshot attached.

Hi @lwang

We removed it in the latest update.

The same can be achieved by using the preview button just below the webhook url or pasting JSON directly into an evaluate block depending on your use case.
