Does the Federal Arbitration Act require enforcement of a bilateral arbitration agreement providing that an employee cannot raise representative claims, including under the California Private Attorneys General Act?

QUESTION PRESENTED Does the Federal Arbitration Act require enforcement of a bilateral arbitration agreement providing that an employee cannot raise representative claims, including under _ the California Private Attorneys General Act. In other words, does the FAA and this Court’s precedent (e.g., AT&T Mobility LLC v. Concepcion, 563 U.S. 333 (2011) and Epic Systems Corp. v. Lewis, 138 S.Ct. 1612 (2018)) overrule the California Supreme Court’s precedent in Iskanian ov. CLS Transportation Los Angeles, LLC, 327 P.3d 129 (Cal. 2014)? This precise question is already pending before this Court in Viking River Cruises, Inc. v. Moriana, No. 20-1573 (certiorari granted Dec. 15, 2021) and has been raised in numerous past and pending petitions for certiorari.
