Need to undo the two screws through the back of the cistern into the wall.
Undo the two screws at floor level into the side of the pan.
Pull the whole shebang forwards (may need to lift it a bit to clear the floor mounted brackets which are underneath).
When it’s a few inches away from wall you may be able to access the full valve from the rear.
Change this.
Now your real trouble starts- depending on what’s behind there I would renew the pan connector.
Reverse what you’ve done and cross your fingers that it doesn’t leak where you can’t see it.

To be honest you are better off getting a plumber in for these- then if there’s a leak it’s down to them to sort it.
