Hi!

you can use view formatting json for this:

Example code for creating this button and download image: 

{
  "$schema": "https://developer.microsoft.com/json-schemas/sp/column-formatting.schema.json",
  "elmType": "button",
  "style": {
    "flex-direction": "column",
    "width": "80px",
    "border": "none",
    "border-radius": "3px",
    "margin": "10px 0"
  },
  "attributes": {
    "class": "ms-bgColor-themePrimary"
  },
  "children": [
    {
      "elmType": "a",
      "txtContent": "Download",
      "style": {
        "color": "white",
        "text-decoration": "none",
        "padding": "12px 0px 12px 0px"
      },
      "attributes": {
        "target": "_blank",
        "href": "= @currentWeb + '/_layouts/15/download.aspx?UniqueId=' + [$UniqueId]"
      }
    }
  ]
}
