Apr 7, 2022 at 16:45 comment added მამუკა ჯიბლაძე Pity I cannot say more, but at some point I was trying to unravel the structure that begins with the set of objects $G$ and morphisms generated by $[x,y]:yx\to xy$. I believe I managed to show that this much comprises a braiding and that the conjugation action is not more and not less than that. Most likely for topological or simplicial groups one can build on top of that all the higher structure but I never came to looking into that.
