Prerequisite
Make sure you complete all steps as mentioned in this document
https://dbatracker.com/2020/05/28/setup-2-node-rac-dataguard-for-2-node-rac-primary/
once it is done you will have 2 node RAC at both primary and standbu site up and running and in sync.
Tnsnames.ora
make sure these tns entries exists on all 4 nodes (2 primary and 2 standby) DATABASE oracle home (not GRID oracle home).it is also mentioned in above post for setting up dataguard
