While the right to testify before a grand jury is significant and "must be scrupulously protected" (People v. Brumfield, 24 N.Y.3d 1126, 1128, 3 N.Y.S.3d 295, 26 N.E.3d 1149 [2015] [internal quotation marks and citations omitted] ), "a prospective defendant has no constitutional right to testify before the [g]rand [j]ury" (People v.
