Despite some initial concerns, the teacher is confident that her students mastered the lesson.

this is a sentence.
here the teacher is confident is the independent clause and that her students mastered the lesson is a dependent clause(noun clause) .
my question is that the dependent clause here is modifying or giving more information about the adjective confident (why the teacher is happy? )
and therefore (that her students have mastered the lesson ) should be a adverbial clause as it behaves like an adverb by modifying adjective confident .
correct me i am wrong
