Accidental Upload of Non-Owned Asset to Substance 3D Community – Need Help Removing

Hello,
I accidentally uploaded a 3D model to the Substance 3D Community Assets platform that I do not own.
The file is called "englishbulldog by alexlashko freesample".
I intended to use it privately for texturing in Substance Painter, not to share it publicly. The model is licensed under Creative Commons (CC BY) and belongs to the creator Alexlashko, but I didn’t provide full attribution and do not want to violate any terms.

Please remove this asset from my uploads or advise me on how I can remove it immediately.

Thank you and sorry for the mistake.
