I asked Auffusion regarding their license

The reply from happylittlecat2333:

Yes, you can monetize your video with sound effects from FoleyCrafter. However, since it uses a checkpoint from Auffusion, which is trained on non-commercial datasets and thus has a non-commercial license, please acknowledge Auffusion and the datasets. You can do this by including a GitHub link, an arXiv link, or simply mentioning the name of Auffusion.

Link to Auffusion issue

So I simply just add the following three lines to my video description.
FoleyCrafter is based on Auffusion.
