How to create a chat conversation between customer and agent

I was able to manually create a chat conversation between a customer and agent who was listening on a Queue.
I used Genesys Cloud Developer Tools (https://developer.genesys.cloud/developer-tools/#/webchat).
I selected the deployment and queue and then click "Start Chat".

But I need to create around 10000 chat conversations between customers and agents.

Will appreciate if someone can provide me with some pointers on how can I achieve that?

I assume I will need to use REST API's to automate the process of creating chat conversations.

@arun_o_gupta Please be aware that you must not perform any load testing on the platform without pre-approval. Conducting unauthorized load testing may result in the suspension of your org as it may be construed as executing a DDoS attack on the Genesys Cloud platform. Please open a case with Genesys Cloud Care to discuss and seek approval for your load testing plans prior to conducting any testing.

Once you have gotten approval for your load testing, you can use the Guest Chat APIs for web chat v2 to programmatically conduct chats as a guest.

Check out the new integrated Web Chat and Web Messaging dev tool we recently released: https://developer.genesys.cloud/devapps/web-chat-messenger

Thanks so much for your help. I will first try to automate the insertion of a single chat conversation.
Once successful, I will open a ticket with Genesys Cloud Care for any type of load testing.
