Allez Sprint Frame, 30mm Spindle Cannondale SI cranks.. how does this BB situation work?

So the frame has this (what I believe to be BB30?) bottom bracket, they’re internal as pictured and sit flush. The diameter is fine for the 30mm Cannondale SI cranks I have to pass through, but I don’t have any spacers and obviously no BB cups to secure the cranks / chain line.
What am I going to need to buy? Is there a simple solution or is it simply new BB time, what kinda BB would I need for that frame + cranks?

i will never buy a BB30 bike again. Depends on what crankset you have, there should be plastic washer cover and compressible washer ring.
Cannondale Si Hollowgram cranks, and nah sadly I got them second hand I’ve got 1 small thin washer on the back of the chainrings but nothing near the kind of gap / clearance I have when they’re in the frame

Amazing thanks! I did briefly google but I didn’t immediately see a set of spacers / washers like that that I seemed appropriate.
you can get parts on eBay or online pretty easy. Here are ways to fix the creaking if you experienced it in the future. I just didn't want to deal with it on my CADD12.
