Flamingo addon

Hi!

I have used Caldera Forms for a long time but now discovered that it is no longer supported. I therefore consider using Contact Form 7 together with Flamingo instead.
My use case is a delivery form where our customers register when to make a delivery. We then need to register details about the delivery. For this I have made a plug in on top of Caldera Forms which reads the submited data and stores it in a separate table. I have then created and admin page which uses this table.

The Caldera Forms plugin hooks into a Caldera Forms through an add_actionlike this:

add_action( 'caldera_forms_submit_complete', function( $form, $referrer, $process_id ) {
    global $wpdb;
    if( $form[ 'ID' ] === 'CF5b2980d1b0e63' ) {
...

(I can include the complete plug in if of interest).
Could I create a similar plugin on top of Flamingo?
Would I use add_action then or something else?
Which parameters should I use?
Other sugestions for solving this use case?

Best regards,
Arne
