Download multiple files from Gallery (Collection of MULTIPLE SharePoint Document Libraries)

I have created a Power App to aggregate 5 different SharePoint Document Libraries into one using a Collect. What I want to do is add a checkbox, to the gallery item, and then a button to download all those selected.

I think I am running into an issue since these are all disparate Document Libraries, all of which have different URLs.

On my gallery check boxes OnCheck property:

Collect(varCheckBox, ThisItem)

On my gallery check boxes OnUnCheck property:

Remove(varCheckBox,ThisItem)

On my Download Selected button's OnSelect property:

ForAll(
    ShowColumns(
        varCheckBox,
        '{Link}'
    ),
    Download('{Link}' & "action=view")
);
Clear(varCheckBox);
Set(
    varResetCheckBox,
    true
)

My use of "& "action=view"" is a workaround that I've been using to force file downloads rather than launching in a browser.

Clicking Download Selected only downloads the first checked box (first item in the varCheckBox collection. How can I modify what I've done to download everything that is selected?
