For those that did PT before surgery, what did it look like for you?

Preparing for endometriosis surgery (diagnostic one) and I been doing pelvic floor PT for a few months now but now I’m really trying to learn if I’m supposed to relax my pelvic floor or strengthen it?
I was thinking I can strengthen it for 3 months then the month before surgery aim for relaxation?
But when I google that it says not to do that and only aim for relaxation?
Can you please tell me what your experience was like preparing for surgery and after?
