Integrating SVED to layer lang#latex
I'm completely new to vim, and I've installed SpaceVim on top of nvim. I'm trying to have [SVED](https://github.com/peterbjorgensen/sved) working in this context. It complements vimtex to allow forward/reverse search when using Evince as a PDF viewer. If I'm right, vimtex comes with your lang#latex layer.

Inspired by what I found on [SpaceVim doc](https://spacevim.org/documentation/#custom-configuration), I've added 

```
[[custom_plugins]]
  repo = "peterbjorgensen/sved"
  merged = false
  on_cmd = "vimtex-reverse-search"
```

to `~/.SpaceVim/init.toml`, with or without the last line, but it does not work. I'd be happy if you could help me to configure it correctly, and perhaps it is worth considering integrating it into SpaceVim.
