I don't know your Oracle version, but if you can:

create snapshot xyz ON PREBUILT TABLE etc. ...

Then your Oracle version is OK.

There is more than one way to create the tables in the secondary database. I usually create the empty tables, then for each table:

exec dbms_snapshot.refresh('TABLE_NAME','C')

set up the refresh group and refresh schedule (usually every five minutes for me).

This certainly isn't the only way to do it.

I have never set up a failover site like this. I just do it this way because we have so many frequent changes, that I do not want to completely lose a snapshot table whenever I must temporarily drop a snapshot in order to make some change. Sometimes in our test environment, we might want to split a replication pair to run independently for a while. Then put replication back in later.
