I’d give it another try, with a simpler bidet. Japanese bidets are overcomplicated butthole spas, you might have used ithe wrong settings.

I rinse with water while aiding with my hand to make sure it’s all clean and then use a dedicated towel to wipe it dry. I guess it’s slightly more inconvenient than just wiping but I’ve been doing this for well over 10 years and don’t really think about it.
