Just because an argument contains a logical fallacy doesn’t mean the argument is necessarily incorrect.
An example:
Person A: This food is better for you because it’s all natural
Person B: appeal to nature, therefore you’re wrong and it’s not better for you
The food may well be much better for you but person B has assumed that the opposite is true because person A has used a logical fallacy and has themselves fallen into a logical fallacy.
It’s still detrimental to the conclusion to use a fallacious/invalid argument, as it will not convince people of the conclusion, even if it happens to be correct for a separate reason - in which case you should say that reason, not the fallacious one.

You mean conclusion. A correct conclusion can be arrived at via fallacy, and the argument is fallacious but the conclusion may or may not be correct.
