Ripped Models Have no Armatures

[tama]

I apologize, I don't know where else I could post this

So, I finally managed to get those models from Dragalia Lost, but they all exported as .obj files, so they can't be posed... I wanted to upload them to TMR, but I doubt that they would accept an unrigged model. Should I try to rig them manually, or just try to upload them as they are ?
