How to retrieve tweets that directly mention me, excluding replies?

[tttjj80]

I'm building a Twitter bot with Tweepy that replies to mentions.
I'm using the API: https://api.x.com/2/users/:id/mentions.
However, I get the original tweet that mentions me and replies to that original tweet from api's response.
How can I filter out the latter?
I've reviewed the Tweepy documentation multiple times but haven't found a solution. Any assistance would be greatly appreciated!
