since your bottom bracket doesn't have that lip (which none of the adjustable-chainline ones should), adjusting the chainline is as simple as "shift the bottom bracket unit in the shell"
since there's no lip on the outside to act as a stop you can add all the spacers in the world and they're just going to fall off, there's nothing there for them to well, "space"
install the bottom bracket and drive-crank as you normally would, find out what direction the chainline needs to go in. ie: do the cranks need to come closer inboard or further outboard?
remove the cranks, loosen the drive-side of the bb (if it needs to go outboard) and tighten the non-drive side down against it. vice-versa if it needs to go inboard.
reinstall the cranks and check again.
repeat until your chainline is correct. one side could very well extend a little bit outside the bottom bracket shell. that's okay. the other side will be sunk into the shell. that's okay too.
