Groove, how to cancel downloads.

[minipot]

I started a big download of music from groove on my windows 10 tablet, thinking I'd set the storage location as my Sdcard - but I hadn't. Now I have the download trying to take up a tonne of space but can't find a way to cancel it, at the minute I'm just not using groove because every time I try to reopen Groove the download restarts.
Thanks for any help.
