When I click the Icon, this shows me the error. Anyone could help?
Hi @neljohnbayalas18,
Thanks for reaching out.
It seems like your setup is correct. I’ve tried to recreate your use case, but the issue you have reported is not reproducing on our side. Will it be convenient for you to share access to your app so I can take a look?
For this please add our support@zeroqode.com email as a collaborator of your app (disregard the warning, our email can be added to the collaborator list even if your app is on the Free plan). And please let us know the page where you are using the plugin.
Looking forward to your reply 
Thanks!
