Are Tags in MailChimp no longer supported?

[poonasor]

I'm trying to add some tags to each subscriber but nothing here or what I'm finding online is working.

I've tired subscribing then adding the tags
Newsletter::subscribeOrUpdate('[email protected]', ['FNAME' => 'Rince', 'LNAME' => 'Wind'], "subscribers");
Newsletter::addTags(['family'], '[email protected]');

I get the following:
Call to undefined method Spatie\Newsletter\Drivers\MailChimpDriver::addTags()

I've tried passing it in as a 4th arugment:
Newsletter::subscribeOrUpdate( $request->email, [ 'FNAME' => $request->name, 'LNAME' => $request->last_name ], 'subscribers', [ 'tags' => [ 'tag1' => true, 'tag2' => true ] ], );
