Invoice processing - issue

Hello Everyone,

I am trying to create a Invoice extraction process using Document understanding ML extractor etc. Now after extraction, I have added step to create action for validating the invoice result in Action center.

But this holds the bot till some one validates the invoice in Action center.

I want to make a bot such that bot does not remains idle, and if it is waiting for someone to validate the invoice, in the mean time it starts picking up the next invoice for processing, and so on, as soon as validation task is over, it finishes the pending task of that invoice, so this will make sure that bot is not idle and is utilized to its best when running on orchestrator.

Can you suggest a detailed strategy for this.

Regards
Ankit

Invoice 1 - Pending for Validation
Invoice 2 -
