Oatmeal and steel-cut oats do not contain amylase enzyme, which is
necessary to convert the starchy oats into sugars. Lager malt
is a good source of amylase, or you can add diastatic malt syrup
or supply the enzyme from a refined source. The advantage of the
lager malt is that the husk material forms a grain bed which will
act as a filter when you sparge. Ale malt will work also, but
is not quite as high in enzyme content.

Pale malt is not an adjunct. (Most) anything that is malted supplies amylaze
enzyme, anything that has not been malted doesn't, and is callled an adjunct.
Other than the terminology, you're on the right track.
