How can i change the default downloads folder in Ubuntu?

I have been learning coding and slight amounts of hacking by dual-booting windows and Kali Linux (Don't worry this is not about any of those oses). The only problem was that I had to reboot in Kali Linux to boot into Windows and vice versa. Later, I learned that I could use something called W.S.L where I could run Linux bash with Windows. I got happy and I installed the Ubuntu terminal. The problem is, that ubuntu says there is a folder before the Partitions called MNT and there are multiple folders like that. It says my windows downloads folder is in MNT/c/Users/<insert name here>/Downloads. Now, I cannot access my ubuntu download folder from windows, so I want to change the downloads folder of ubuntu to one of the windows. I could typically use ubuntu tweaks, but I cannot use any ubuntu applications (or at least I don't know how to). What should I do?
