In the Contact Flow builder, what block must always come before a 'Transfer to queue' block?

In the context of the Contact Flow builder, the 'Transfer to queue' block is specifically designed to send the caller to a defined queue for further handling. To ensure that the transfer occurs smoothly and that the call is directed to the right queue, the 'Set Working Queue' block must precede it.

This requirement exists because the 'Set Working Queue' block establishes which specific queue the call will be transferred to. Without this configuration, the system would not have clarity on where to send the interaction, potentially leading to misdirection or confusion in handling the call. By specifying the working queue beforehand, it enables the Contact Flow to function effectively and make appropriate routing decisions based on the defined parameters.

In the scenario described, while the other options are relevant in certain contexts, they do not directly fulfill the prerequisite necessary for the 'Transfer to queue' block. Therefore, having a 'Set Working Queue' block in place ensures a clear and accurate transfer process.
