Is dropshipping halal?

I just wanted to know if dropshipping business is halal. I found a video on youtube by Sheikh Assim al Hakeem who says that dropshipping is not permissible. Other than that, I did not find any other sources that directly say that dropshipping is haram. The link to Sheikhs video is here: https://www.youtube.com/watch?v=9BrIHPzPc64
