Shower Waterproofing

Hi, I'm diying a full bath, first time doing this. I'm a young mom and inexperienced in this area. Since I couldn't afford a tile installer to do the job (and to be honest is quite a luxury because the prices are high in the sky) I decided to do it myself by following your YouTube channel. I had to self-level the floor, it was 3/4" out of level it went wrong. I did the prep right I ground the floor, sealed and primed + metal lath but it didn't level right so I had to grind the self-level concrete. It was hard but turned out right.

On the shower I invested in a custom made Tile ready trench pan, my shower is 34 1/2" x 56" so I had to. On the walls, I install a go board with Kerdi screws and washers. I didn't read the installation manual and didn't use the caulk sealant that the manufacturer recommended. I know is the manufacturer and I just violated the warranty by using LATICRETE HYDRO BAN ADHESIVE AND SEALANT paired with goboard which they didn't recommend on the approved material list. When I went to the store an associate said those products were almost the same, one with better quality than the other but basically built out of the same material. I couldn't afford Hydroban foam board so I went with Go board and Hydroban sealant caulk. Am I doing it right? Will this work or break down the road?
