Bosch Detergent Door nightmare

So…Im not a huge DIYer but I thought I would tackle this door dispenser thing on my own. Not so sure that was a smart idea.

I think I need to order part number AP2802332.

My questions are:

Should I pay someone to put this back together or can I do it myself?

Do I need a whole new dispenser or just the spring and the little plastic thing that is broken in the picture?

Lastly, Does it need to be repaired at all? Can I just leave it and use the dishwasher broken?

Thanks for your help.
