It all depends on what kind of wall, solid wall or drywall?
In the case of solid walls, the "niche" must be bricked up after the support system is installed with thinner stones so that the sliding element can slide freely in the wall pocket, then the interior plaster . There are often problems finding a standard frame here, so it will probably be custom made.
As an alternative, I can personally recommend the drywall system from Knauf, 125-150mm wall thickness, door can vary 3-4 times as you wish, height and width can be found on the Knauf website!
I've built about 250 myself in a building project (100 apartments), in the sliding door area there are problems hanging on the wall, but the problem is not much less in the solid version.
Problems? Yes! Improper installation will cause problems with every door!
