Run JavaScript on Gravity form button click

I have a gravity form with a nested form in it, I want to run a javascript function on adding and editing and entry, is there a way to add onclick attribute using hooks? or any other methods.

some similar codes I’ve found,
this adds custom class:

add_filter( 'gpnf_template_args', function( $args ) {
	if ( $args['template'] === 'nested-entries' ) {
		$append_classes     = 'class-a class-b';
		$args['add_button'] = str_replace( 'gpnf-add-entry', 'gpnf-add-entry ' . $append_classes, $args['add_button'] );
	}
	return $args;
} );

and this allows to customize the text:

is there a way to combine these to run a javascript function on click?
