    matches: ["myurl"]
  }

  export const getInlineAnchor: PlasmoGetInlineAnchor = () => document.querySelector(".olx-focus-header__content")
  export const mountShadowHost: PlasmoMountShadowHost = ({ 
    anchor, shadowHost 
  }) => {
    anchor!.element!.insertBefore(shadowHost!, anchor!.element!.nextSibling)
  }

  export const getStyle = () => {

    return style
  }
