How to embroider portrait orientation on a hoodie or sweatshirt on Brother PR680W

As the title suggests, I have a 12x8inch hoop and I'm trying to embroider portrait on a hoodie, however due to the bobbin arm underneath, the fabric on the hoodie has nowhere to go. I've tried turning the fabric inside out and putting the hoop on the machine but then the arms have nowhere to go? Any help please?

I considered getting the jumbo 14inchx14 hoop but apparently it's not compatible? But some sites say it is.

Thank you!
