freedom UI - how to execute code when creating a record for the first time

Hello,

I need to call a code once a record gets created for the first time. This worked using the following:

handlers: /**SCHEMA_HANDLERS*/[
			{
        request: "crt.SaveRecordRequest",
        handler: async (request, next) => {

however what this does is execute the code for each attribute value change, which is not what is needed. How can I call this exactly once just when the record is created for the first time and that's it, without having to call it again for each save request? Thanks

Note: I have tried replacing SaveRecordRequest with CreateRecordRequest, however the code was not executed once saving, or on any save.

Best,

Mohamad
