Process to add Additional Trade Name in the same GST No

What is process to add Additional Trade Name under the same GST No ?
The Goods and Services Tax Network recently implemented a new feature that allows you to add a “Additional Trade Name” (not the same as the ordinary trade name) to the same Goods and Services Tax Number.
Having various trade names under the same legal name or the same Goods and Services Tax Number will be advantageous to a company. The facility is open to both new and existing taxpayers. Existing taxpayers can apply for this functionality by filing an amendment application under the core field.
GST Dashboard => Services => Registration => Amendment
But New taxpayers, can use this option when completing out a new registration form.
