Yes, you can customize the options available in the stream UI by creating your own flow for videocalls. You can find the option to do so here.

You can see the videocall flow as a way to customize the call experience according to specific use cases and company needs. You can create as many flows as you want, allowing your agents to use specific interfaces based on their or customer's needs.

When you customize a flow you have the option to disable video, screenshare, or to define if the link generated should expire after the call.

You can even define if a transcript or a summary should be added to the linked ticket once the call is ended.

Once the flow is created, agents will find the option available within the linked CRM. In the example above, you can see how agents can access all available flows using the widget on the bottom part of the Zendesk ticketing UI.
