How to convince room mate to shower

Can someone give me some ideas on how I can be as gentle as possible when it comes to telling my roommate to shower. She smells very bad and hasn’t showered in well over a week. We have all being dropping subtle hints about showering like after we shower we are like “you can shower and use my stuff.” And we put a heater in there because we thought maybe she found it too cold

I don’t want to make her feel attacked I just don’t want to smell that and I’ve offered up my soap to her and been like “smell this it smells so good.” To give off little hints.

I’m really not trying to be mean, but everytime i walk by her or her room I get a whiff of stink and I’m like wondering if she’s just too insecure right now or feels uncomfortable because she just moved in, I don’t know. I’m just so confused. Maybe it’s depression so I’m not judging her, I just don’t want her to stink.

Her room is not even dirty, it’s like the smell just followed her to her room and because that’s where she is all the time it stayed there.

Please be nice on this post, being mean is not where my hearts at and I don’t want anyone to drag her.

Edited: somehow my other roommate talked her into showering so she’s currently in there. I know it sounds like depression I just didn’t know how to go about that because I’ve also been in a depressed state before where I dissociated and lacked hygiene BUT, I didn’t have help with that. I just snapped out of it by myself and brushed out my matted hair and went back to normal like my brain came back on.

But no she’s in there showering. Nobody was mean to her or made her feel bad, so I’m proud of that.
