DWAC per DTCC

I think I understand DRS (book) and have done so with xxx shares of GME.

Can anyone compare contrast DRS (book) and DWAC (https://www.dtcc.com/settlement-and-asset-services/securities-processing/deposit-withdrawal-at-custodian )of GME shares?

DRS your GME

All those who have DRS’d and Booked are an activist investor group.
