Am I the first person to install a custom rom on this tablet model?

So, after struggling a lot to get mtkclient working and getting stuck in preloader mode for total of 6 days, my Lenovo tab m9 is finally running a custom rom.

After I have done it, I searched specifically and didn't find anyone online even mentioning attempts to do it, so I'm likely the first person ever to install a custom rom on it, or at least I'm definitely one of the first. Others could have not posted about it.

I'm so happy I finally got this thing rooted. Also debloated and completely degoogled by installing that custom rom.

Also the touchscreen input lag was horrible before, it's better somehow after installing  different os. It's still noticable a bit, but not that bad. I can finally play rhythm games on it yippie!!!!!!!
