How should I understand 追加で in this sentence?

Should I understand 追加で as noun + で particle to mean additionally in an
adverbial way or should I understand it as another form of the verb form 追加して?
I recalled seeing it used this way before where the speaker just says を + verb
but instead of fulling turning it into verbs by adding する they just say the
verb root + だ or で. Is my observation correct and what is it in this case?
Thank you




There is no such thing as "de-form of a suru-verb." This 追加 is a simple noun
meaning _extra/addition_ , and this で is a case particle to mark a
condition/scope.

Similar examples of `noun + で` include 合計で ("in total"), 割引で ("at a discount
price"), 確認で ("for conformation"), 一人で ("alone"), 土足で ("with one's shoes on"),
本気で ("seriously"), 笑顔で ("with a smile"), etc. All of these work adverbially.
