Email before download pdf file

Hi there

I have a page with several pdf files (in several) languages
I would like to have useres to give an e-mail before being abel
to download a pdf file.

I tryid the:
contact form 7 – download monitor – email before download thing
Here: https://wordpress.org/plugins/email-before-download/

But i cant use that.

On my page i have a small flag (danish
1. Lets say the user clicks on that.
And then it askes for a e-mail before they can download.

On the “Email before download” i have to send useres to a
specific page – and then fill out the form there.

But is there a more easy way. Ex. a download plugin
where users need to fill out a e-mail form.

Really hope you can help

C yaaa | Cheers
