Removes all connections at the given identity (or just one if endpointId provided) from channel contextGroupId. If no target is specified, it removes the sender from their channel.

This is a wrapper for interop.removeFromContextGroup.

Example

removeViewFromChannel = async (view) => {
    await fdc3.leaveCurrentChannel(view);
}

getLastFocusedView()
    .then(lastFocusedViewIdentity => {
        removeViewFromChannel(lastFocusedViewIdentity);
    })
