One suggestion would be promoting your novel on social media accounts (not too many because you don't want to spread yourself too thin), such as Instagram and Twitter/BlueSky. You can also try to network or get involved with the Tapas community, such as joining the official Tapas discord, entering Tapas contests (if it's relevant), participating in forums, or trying out the promotional threads.
Another helpful piece of advice that someone once shared is: If you don't get the word out, then no one will know that it exists.
