Is it possible to still use rtweet R package to retrieve tweets from Twitter

Question

I have made an app that retrieves tweets using the function rweet::get_timeline (in the rtweet package).

The app suddenly stopped working with the following error message:

Warning: Error in : Twitter API failed [403]. Check error message at https://developer.twitter.com/en/support/twitter-api/error-troubleshooting

• You currently have access to Twitter API v2 endpoints and limited v1.1 endpoints only. If you need access to this endpoint, you may need a different access level. You can learn more here: https://developer.twitter.com/en/docs/twitter-api/getting-started/about-twitter-api#v2-access-leve (453)

According to one Twitter page, the free tier does not seem to allow tweet pulls (see screenshot below).

Just to have this perfectly clear: Does this mean that it will now longer be possible to use rtweet::get_timeline (to retrieve tweets from different users)? Thanks for any information that might help clarify this!
