How to test if record is created or not?

Hi,

Im using Supabase and would like to create a record if the ID do not exist in the table.

Im using Backend Call > Insert Row. The ID (guid) is the primary key of the table, so if it already exist Supabase would return an error.

I would like to do one thing if the ID is not found in my table; otherwise, I will do something completely different

Thanks :-)
