I used this plugin in CMSpage. When the subscribe button is clicked no action is performed and redirects to the same page in which the formSubscribe component is added. The users are not added to the subscribers' list either. I added the formUnsubscribe component to another page. The formProfile component is also added to the same page in which there is formSubscribe component. I can't understand what I am doing wrong. The process to add the plugin is also not clear in the documentation provided.
Here is the link to the plugin.
<form name="form-subscribe-andradedev" id="form-subscribe-andradedev" data-request="formSubscribe::onAddSubscriber" data-request-update="'formSubscribe::alert': '#result'">
<input type="email" class="form-control" name="email" placeholder="* Email" required>
<input type="hidden" name="latitude" id="latitude">
<input type="hidden" name="longitude" id="longitude">
</form>
