Pay with other waves asset

I’m building an ECwebsite using the Waves token used in the community.
I set the currency option of WooCommerce’s General setting to Waves, and I set AssetID and AssetCode of the payment method setting, but the AssetID is not included in the checkout QR code.
Like WNET and ART coin, how can I get a QR code of an address like “waves://[waves address]?amount=[amount]&attachment=[attachment]&asset=[asset id]”?
And, can I confirm that the remittance was successful even with payment with that asset, token?

P.S. As a thank you for answering my question, I’ve done a Japanese translation of this plugin!
