Interaction.updateState >> Conference / unhold Customer

[fransiska.hendra]

hi Everyone,

just wondering if is there any way in this https://developer.genesys.cloud/platform/embeddable-framework/actions/Interaction/Interaction.updateState, we can do conference ?

I try to do consult to a flow:
type: 'PureCloud.Interaction.updateState',
data: {
action: 'consultTransfer',
id: id,
participantContext: {
transferTarget: 'ec59e31f-3d28-4c0b-85ef-a85f5262225c',
transferTargetType: 'address'
}
}
});

connected 3 parties, but customer is onhold, and i am trying to unhold customer using this code:
this.sendMessage(component, {
type: 'PureCloud.Interaction.updateState',
data: {
action: 'hold',
id: id
}
});

but not succesful :

Hold or Un-hold function only affecting to agent, just wondering if there's a way to un-hold customer?

Thanks for any advise.

Fransiska
