Everything action you do on Nostr, posting, liking, replying can be called as 'events'. Each event has a 'kind' number which describes what type of event it is.
What you're looking for is long form content (kind: 30023)
The following are some clients that support this event kind:
Yakihonne: https://yakihonne.com/
Habla: https://habla.news/
Highlighter: https://highlighter.com/
Not all twitter-like clients we use display this event kind on your profile by default.
Amethyst does support it on Android though. You can always share a link on your preferred twitter-like client after publishing on the long-form client. The post will still be nostr-native and people can directly zap it as well.
