PDF Previewer keeps hogging Window Focus when executing texlab.build

[NicolasSchuler]

Hi,

I'm currently struggling to set up the previewer for my LaTex PDFs.
On Neovim, when I save my file, it automatically builds the PDF, and the terminal window keeps the focus. On Helix, however, my PDF viewer grabs the window focus (which is annoying because I need to switch focus again).
This is my languages.toml:

[language-server.texlab.config.texlab.chktex]
onOpenAndSave = true
onEdit = true

[language-server.texlab.config.texlab.forwardSearch]
executable = "zathura"
args = [ "--synctex-forward", "%l:%c:%f", "%p" ]

[language-server.texlab.config.texlab.build]
forwardSearchAfter = true
onSave = true

executable = "latexmk"
 args = [
  "-pdf",
  "-interaction=nonstopmode",
  "-synctex=1",
  "-shell-escape",
  "%f"
  ]

[language-server.harper-ls]
command = "harper-ls"
args = ["--stdio"]

Platform
Linux (EndavourOS)

Terminal Emulator
kitty 0.38.1

Installation Method
pacman

Helix Version
helix 25.1

I would appreciate any help. Thank you very much in advance.

Bests
