Hello community, I noticed that this stair step in my european 60ies house was a bit cracked so I broke it off completely. How would you fix this? Some mortar or tile glue? Does it need some kind of rebar?

Thanks a lot for your reply! I'm not sure if I get it though. I attached another picture to my post that shows the step from the top. The part missing is a lot of material, I'm not sure how breaking everything up and glueing the tiles back should work. I'm confident that I could somehow model the little structure using some goey material and then glue the tiles back and apply grout but I'm not sure about the stability of this.
i could also just glue the whole block back in place using 2k glue or cement.
What is under the dried adhesive here? If you were to scrape off. The adhesive what is that?
Oh snap. I see that now. I didn’t catch that before. If it were me I would indeed try to apply a backer substrate of some type. You’ll just have to look around for something the proper thickness but things that come to mind are backer board like you would use in a shower tile application or maybe hardy board? Or even attempt to just build it up with concrete but to do that you’d need to create some holes in the base that it sits in so that it has support and something to hold it better. Not sure about that though.
