RSS feed for Gettr, Gab, Sayches, etc?

I tried to find any common class in the html code of Gettr, but could not find anything useful. Is there any way to get an RSS feed from Gettr? And what about the other alternative plattforms competing with Twitter?

Do they offer public access or do they require login? If login is required Feed Creator can’t be used at the moment. And usually for social media sites we recommend something like RSS Bridge GitHub - RSS-Bridge/rss-bridge: The RSS feed for websites missing it
