Hi
You can use Corvid or Wix paid plan app
But we can’t use “Role”
as this property is a get only
We can’t change the role of the user using code
So workaround is to use a database
if the user is Paid for that software
Update the database with the email
And on the page, query that email
to show/hide the download button
Or
You can create a One time payment using Wix paid plan app
But this won’t be connected to Wix store
