I had the same concern when I was setting up my database audit for executions. It's because RPC statements are not logged as mentioned in the Considerations section of the documentation here:
https://docs.microsoft.com/en-us/sql/relational-databases/security/auditing/sql-server-audit-action-groups-and-actions
If you start a trace and look for the executions, you'll probably see that the one from your app initiates as RPC:Starting and the one from SSMS will be SQL:StmtStarting.
