I am doing a simple task. Code is already working. Following are the steps:

using this post: https://stripe.com/docs/checkout/integration-builder

1. purchasing ticket from UI

2. creating checkout session in the backend and passing requried data. These all is working fine.

        const session = await this._stripe.checkout.sessions.create({
          payment_method_types: ['card'],
          customer_email: email,
          line_items: [
             {
                 price_data: {
                 currency: ###,
                 unit_amount_decimal: ###,
                 product_data: {
                      name: ###,
                      description: ###
                 }    
             },
             quantity: 1
           }
        ],
        payment_intent_data: {
            on_behalf_of: ###,
            transfer_data: {
                destination: ###,
                amount: ###
        },
        metadata,
        statement_descriptor: ###
     },
     mode: 'payment',
     success_url: successUrl,
     cancel_url: cancelUrl
   });
   

code is working fine and I am able to get the payment done and it is reflected into my main account with metadata and other fields.

Issue: I want the same metadata into my connected account where I am transferring money so that we can share the same metadata. There is a metadata section into payment inside the connected/destination account. That's where I want to add those details. Is there anything else I need to update like charge or transfer or anything? I tried updating transfer but none of them reflected metadata into the destination account.

Where should I add what params to get metadata into my connected account? Any help will be great. Thanks
