'camouflagedly' originates from French, specifically the word 'camouflage', where 'camoufler' meant 'to disguise'.

'camouflage' was borrowed into English from French in the late 19th century; English formed the past-participle/ adjective 'camouflaged', and the adverb 'camouflagedly' was later formed in English by adding the suffix '-ly' to the adjective.

Initially it meant 'to disguise', then developed the sense 'to conceal by blending with surroundings', and now the adverbial form means 'in a concealed or disguised manner'.
