Background

For users in the treatment group who already have an account but are logged-out, if they click the bookmark and view the dialog CTA, they may click "log in" and log into their account. Given this is a signal they want to use the ReadingLists feature, we need to opt them into the beta feature.

Requirements

Technical requirements

There are 2 things we need to achieve:

1. We need to target users in the treatment group who have an account. This means they will have clicked "log in" from the CTA dialog in the experimental UI.
2. We need to opt those users into the "Saved pages" beta feature on login.

Some ideas:

@Jdlrobson suggested the onLocalUserCreated hook to set a preference for a new user, like so:

public function onLocalUserCreated( $user, $isAutoCreated ) {  
        $campaign = RequestContext::getMain()->getRequest()->getText( 'campaign' );  
        if ( str_starts_with( $campaign, '..' ) ) {  
            $donorCampaign = explode( '-  
            $this->userOptionsManager->setOption(  
                $user,  
                'readlistin',  
                0  
            );  
        }

We could use the onUserLoginComplete hook in a similar fashion. This still leaves the issue of targeting the right users, though.

We could also consider doing something similar to what we will do to track account creations - see T422177, which details how the Growth team has approached this.

@Jdlrobson also mentioned that there's a way to tell that an account was created via the watchstar CTA - maybe we could use that for inspiration.

Acceptance criteria

• Determine how we can opt existing accounts who click the "log in" CTA from the bookmark button into the ReadingLists beta feature
• Document the approach here or in a proof of concept
