How to add image on the margin to the left of a level 1 heading?

Thank you soooo much @aarnent, this solved my issue.

For the archive I have also added the font definition and upper call to the solution.

#show heading.where(level: 1): it => [
  #let dx = calc-margin(page.margin, (page.width, page.height))
  
  #place(
    image(
      "images/Image1.1.jpg",
      width: 1.5cm // Change as you wish
    ),
    dx: - dx
  )
  #text(font: "Liberation Serif",
  size: 23pt,
  lang: "de",
  region: "at",
  upper(it)
  )
]
