Add button for email in list form footer using JSON. Email content must include link to the form

Question

I have the following problem. I have a SharePoint online list for which I have customized the form with JSON. I added an email button which allows the user of the form to open a predefined email with Information deriving from the form.

My problem is that I would like to add a link into the email directly referring to the form so that the receiver of the email can directly reach out to the form to add further input.

Is this possible with JSON code? Unfortunately I am not allowed to use the power platform. Thank you in advance.

Usually, the link to SharePoint list item display form is in this format:

https://contoso.sharepoint.com/sites/siteName/Lists/listName/DispForm.aspx?ID=1

Where 1 is the list item ID (SharePoint default column).

But unfortunately, SharePoint JSON form formatting does not support fetching item ID ([$ID]) currently as we can use it in column/view formatting.

Reference: Can ID column be displayed when configuring a list form header using JSON?

So, you will not be able to add link to list item form using JSON formatting using SharePoint out of the box capabilities.

Additional:

You can create send an email link using JSON formatting. Example:

{
  "elmType": "div",
  "style": {
    "width": "100%",
    "display": "=if([$Title] && [$AssignedTo.email], 'block', 'none')",
    "padding-top": "10px",
    "border-top": "1px solid"
  },
  "attributes": {
    "class": "ms-fontColor-neutralSecondary"
  },
  "children": [
    {
      "elmType": "a",
      "attributes": {
        "target": "_blank",
        "href": {
          "operator": "+",
          "operands": [
            "mailto:",
            "[$AssignedTo.email]",
            "?subject=Task status&body=Hey, how is your task (",
            "[$Title]",
            ") coming along?"
          ]
        },
        "class": "ms-fontColor-themePrimary"
      },
      "children": [
        {
          "elmType": "span",
          "txtContent": "Send Email to Task Owner"
        },
        {
          "elmType": "span",
          "style": {
            "margin-left": "8px",
            "vertical-align": "middle"
          },
          "attributes": {
            "iconName": "OutlookLogo",
            "class": "ms-fontColor-themePrimary ms-fontSize-xl"
          }
        }
      ]
    }
  ]
}

Where AssignedTo is the internal name of person or group column in the list. You can get the internal name of your column by following this article: How to find the Internal name of columns in SharePoint Online?

I am new to JSON and I also cannot use Power suite nor Designer. The workaround I used to obtain the ID, is by creating a calculated column in the List named "RecID" (you can name it as you wish) and entered in it "=ID". That allowed me to use RecID in my JSON code to obtain the current ID. I hp
