I’m lost and don’t know what I should do, or what it is that I don’t know

I see that there is code to generate multiple selectors when using codegen, per
https://github.com/microsoft/playwright/issues/5178#issuecomment-1130731560

https://github.com/microsoft/playwright/issues/9015

https://github.com/microsoft/playwright/issues/29400

However, I tried installing playwright latest and even the alpha versions but I’m not able to get codegen to generate the multiple selectors. Therefore, I cloned the code that has the fix: https://github.com/microsoft/playwright/pull/29154/files

npm run build

npm install -g .

I was basically trying to install the playwright built from the source code globally, in hope that I can run codegen, but I wasn’t able to.
Can someone help me?

Thank you in advance
