How can I accept SquareUp invoice payments in Bitcoin? No POS, no Shopping Cart

[SylviaMorrison]

How can I accept bitcoin for Square invoices?  I currently submit  Square invoices for services but I do not see an option for Bitcoin or other Crypto. I would like to be able to offer Bitcoin as a payment option in addition to the default options that I currently see (credit/debit cards, ACH Bank Transfer, Gift Card)

Notes: I am not using a physical POS, I am not using a Shopping Cart / not using Square Online. I am only using Square invoices.

Accepting Bitcoin is not possible with an Invoice.  I believe the only option is with Cashapp
