I came to say this.
Definitely reach out to coaches and attend some practices as a "try out".
My kids did this - one kid when switching clubs and another when moving from rec to club.
They both "secured" spots before the actual tryout because they fit with the kids and also was able to keep up with the practices.
The actual tryout was just a formality after that.
At the VERY least, attending these "in practice tryouts" will give you a flavor of their practices and drills they run and she'll be more ready for the actual tryout.
It's free to check out club practices in my experience so if you were up for it, you can line up Mon/Wed with one team, Tues/Thurs with another... get a few weeks of practice in leading up to the official club tryout and be super ready for it
Good luck!
(Oh and I'd try to get a feel for the parents... you're going to spend a lot of time with them during the club year... you can't spot the a-hole right away sometimes... but I'd avoid teams with them if you spot one
