I have the following which works in HTML:

<a onclick="__tcfapi('displayConsentUi',2, function() {});">Manage Privacy Settings</a>

However, this doesn't work in AMP since scripts aren't allowed, which I understand.

I have tried using the following but it's not working either:

<amp-script layout="container" script="manage" class="amp-my-custom-script-menu">
    <li><button on="tap:manage">Manage Privacy Settings</button></li>
</amp-script>

<script id="manage" type="text/plain" target="amp-script">
    __tcfapi('displayConsentUi',2, function() {});
</script>

It's not working and I'm getting an error in the console:

[Action] Target "manage" not found for action [tap:manage]
