Tuning Hammerli Hunterforce 900 HELP!

So I purchase this Hammerli Hunterforce 900 from Krale last year. Shot it about 50 times max and decided I’d take the stock off and clean all the factory oils and stuff off the exterior. Well the trigger assembly on here fell out and I’ve tried for months to try to piece it back together with no success. I can’t find anything online that shows this exact trigger assembly only variations of it.

Krale will not help at all, they were terrible to me. I messaged Umarex to see if they will help in anyway. I literately am ready to trash the gun as I truly have tried everything, if you have any experience with these assembly’s or know if they are on any other guns I would GREATLY appreciate it. I would love to get this thing shooting again.
