Better reporting from the BBC than we're used to. Second sentence in the article makes it clear this law is for everyone, not just people with gender dysphoria, and it's about sex, not 'gender':
The proposals, which would allow people in Scotland to self-identify their sex, were passed by the Scottish Parliament in December last year.
Then near the end making it clear that it's about everyone being able to choose their legally recognised sex (including rapists like Isla Bryson):
The reforms are intended to make it easier for people to change their legally-recognised sex by doing away with the need for a medical diagnosis of gender dysphoria - a sense of unease that a person may have because of a mismatch between their biological sex and their gender identity.
Applicants for a gender recognition certificate would need to have lived in their acquired gender for three months rather than the current two years.
I'm hopeful that someone will eventually explain how someone 'lives in their acquired gender'. And what a gender identity is.
