Does the TCPA's definition of an ATDS require a number generator to generate the numbers themselves?

question presented is: Does the plain language of the Telephone Consumer Protection Act’s (““TCPA”) definition of an Automatic Telephone Dialing System (“ATDS”) at 47 U.S.C. § 227(a)(1), and this Court’s holding in Facebook, Inc. v. Duguid, 141 S. Ct. 1163 (2021), require a plaintiff to allege that telephone dialing equipment uses a number generator to generate the telephone numbers themselves, or does it merely require the use of a random or sequential number generator to store or produce telephone numbers to be called?
