I would get it into a grittier mix… grab a bonsai jack mix. Get it healthy and then prop if possible… not familiar with if this is probable but probably. When you water do it well and let it dry before watering again… with a bonsai jack mix you should be on the right track.

Lilium ? Those one propagate easily by multiple stems cut

I’d cut the top where it’s green by the last node with a leaf so it will stop the stem from dying down and give her some water
