User's permission for texture packs

Hello, I have been developing a plugin for a about year now.

In my last update I wanted to add custom textures by using the player.setResourcePack() function. As far as I know when this request is sent for the very first time from a given server, the client will first display a confirmation GUI to the player before proceeding with the download. But the file has been rejected with this message:
"We understand that there's nothing malicious in your code but we don't allow mods to download resource packs/texture packs/any file without the user's permission first"

I am wondering do I have to do some kind of check before calling the setResourcePack() method or I just can't add texture packs this way?

 

I have a project on bukkit and I have uploaded the file there but it was rejected from curseforge.

 

This is the code I have used.

Code:

    @EventHandler
    public void playerJoin(PlayerJoinEvent event){
        event.getPlayer().setResourcePack("https://www.dropbox.com/sh/7rlnpc09veplapx/AACkBZ5jtVaWO6sMOQLB0PH6a?dl=1");
    }

Should I reupload the rejected file?

 

Okay, thank you!
