Are there any editors for script command that allow to fix typos?

I want to record a gif with interaction of my Linux tool (REPL), but it's time consuming to make it perfect without any mistakes when I type the commands. So I was wondering of using script command and then edit it later, but I will probably break the script if I try to edit it. So are there any tools that allow to edit the session and timing from script command? Or maybe something that will allow me to write the code that will be automated in the shell with visual feedback? I asked ChatGPT he suggested to use expect, but the output doesn't look good. It can automate a single executable (my program) but it will don't show the shell prompt, how I type the program name, and execute it. ChatGPT also suggested to use asciinema, but it only animates a fixed text. And I want to animate the interaction with the shell.
