How do I remap a macro in Helix, instead of just adding another keymap alongside the default one?

Question

I move with j-k-l-ñ instead of h-j-k-l and I can't replace the go to line start command with gj and get rid about the gh macro.

[keys.normal}
 g = {j = "goto_line_start}

I tried to do some research but I didn't find anything beyond just disabling the macro with no_op .

Update:

If I try to set the goto_line_end macro to g"ñ" it just removes the new goto_line_start one (and also doesn't remap gl) for some reason
