Not sure where to put custom SQL procedures

[ferdware]

Using the test-plugin template. I created a function to call a custom MySQL procedure "custom.sql"

I tried to run it under the plugin in the following folder
use \Vvveb\TestPlugin\App\Sql\Custom
Folder -> /test-plugin/app/sql/mysql/custom.sql ( Does not work )

However if I put it here:
use \Vvveb\Sql\Custom
Folder -> /app/sql/mysqli/custom.sql ( works fine )

Please advise on the correct usage of custom sql file and procedure.

Thank You.

I figured it out. I copied the contact-form plugin placement of the mysql procs.
