Twitter may let you edit your tweets but only if you are ready to pay them money 

Dorsey had hinted in 2020 that Twitter might never get an edit button as he wants to preserve Twitter's original design which was primarily an SMS, text message service

For the longest time, Twitter users have demanded an Edit button. The feature however was written off by CEO Jack Dorsey, who said that the app will never get the edit button. However, Twitter did introduce Undo button with its Blue subscription, which more or else does the same job. But now Twitter’s head of Product, Kavyon Beykapur wants to know from the users if they would pay for the edit button. Twitter might be working on an edit button, but that could be limited to the paid subscribers only. Beykapur shared a poll on his personal handle asking users to get the option to edit the tweets. He wrote, “f @TwitterBlue let you edit tweets within a few minutes of posting them, would you want to subscribe? Let me know why yes/no in the replies!” Over 68.4 per cent of users have hit the “No” button while only 31.6 per cent of users have agreed to pay for the edit feature. Twitter might be considering the feature, and Beykapur even hinted that the feature would let users edit tweets a few minutes after posting them.
