Need Help with True False Not given qs

Passage said , " The seeds of the fruit can be used to produce oil. This oil is used to protect the skin and it is also used in the cosmetic industry. The leaves of the baobab are also useful. They can be eaten fresh or they can be dried and stored. They are rich in iron and can be used as a medicine. The leaves can be used to treat asthma, insect bites and several other ailments. The leaves can also be used as a sauce for food. The bark of the baobab is also useful. It can be used to make cloth and rope."

The question was The leaves of the baobab tree can be used to make a medicinal sauce.

My answer was Not Given ( because, I think that The passage confirms that the leaves are used as a sauce and that they have medicinal properties. However, it does not say that the sauce itself is medicinal.)

And the system where I took the test is saying that the answer is True , they argued that
the text explicitly mentions that baobab leaves can be used as a sauce for food. It also highlights that these leaves are rich in iron and can serve as a medicine for various ailments, linking their culinary and medicinal uses.

“The leaves can also be used as a sauce for food. They are rich in iron and can be used as a medicine.”

I'm so confused !(
