We actually ordered a bidet kit off amazon and installed it.
Has a plate with holes for the seat screws to go through. The Bidet can be positioned forward/back on slides within that plate, and when the screws are tightened locks the whole thing in place.
That first jet of cool water can be an eye opening experience. But I have to admit, I like it. And my bottom likes it. And there is a lot less "bill butt" smell.
I use half the TP or less than I used to. Mostly for drying, although it picks up a smidge now and then.
At 40$ and a little time to install I consider it a bargain. Should pay for itself within a year or 2.

We are pretty happy with the unit, and how it works but I am a little concerned about its structural strength.
Seems a little loosey goosey. Being mostly made of fairly thin plastic.
