Unable to see the e-Way Bill JSON in Sales Invoice screen

Hi ,

I am unable to see the “e-Way Bill JSON” option on the “Make” menu of Sales Invoice after submitting the invoice.

I followed the instructions on the following link, but was not able to get to the field for JSON eway bill :
https://erpnext.com/docs/user/manual/en/regional/india/auto-generate-e-way-bill-JSON

Does anybody know how to enable it or which fields are mandatory for it to be activated.

Thanks in advance

Regards,
