Ticket Purchase Question

[Porsche4]

I am researching for a November 2024 holiday (likely 8 night stay 7 days in the park). As I live in Australia I have discovered we can pre book exclusive DL tickets via Klook. For Australian residents only they have a 5 day Park Hopper with Genie+ and a 2 day Park Hopper with Genie+ (total 7 park days) for a lot cheaper than if I purchased it through Disney direct or other American based booking agencies. I have purchased tickets through an American Agency last time and had no problem linking the tickets to the "My Disney" App. My question is has anyone had any experience doing this with Klook purchased tickets. Is it basically the same deal, you get a code from Klook and just add that to your App and your tickets appear so that you can then make Park Reservations. I have heard good things about Klook and that they are legitimate but just wondered if anyone has had any direct experience with the process.
