GSTIN and Composition Declaration Not Showing on Bill of Supply

I am a GST Composition Scheme taxpayer. MyBillBook correctly generates the invoice as “Bill of Supply,” but the printed bill does not display my GSTIN and I cannot add the mandatory declaration at the top.

Please add an option to display:

And this declaration:
“COMPOSITION TAXABLE PERSON, NOT ELIGIBLE TO COLLECT TAX ON SUPPLIES.”

Please provide editable header/custom declaration options for Bill of Supply templates. This is required for composition taxpayers.
