Import Passwords from CSV file

I'm trying to import password from a CSV file in Safari. After trying many things with no success (always getting the error that the passwords could not be imported because of the format of the CSV), I wanted to get the "basic" case possible. So I went to the Passwords settings in Safari and exported what I have. This saves a CSV with my current passwords (so I thought the CSV format would be the expected one for importing).

I opened this file in Numbers and removed all the rows minus one, which I edited to add a "test", like this:

Now, when I try to import this one I also get the same error:

I also tried different things like filling the OTPAuth with content or even delete it. No luck.

What am I doing wrong? I just saved the file that Safari gives you and tried to imported again 🤔

I'm out of ideas here... any help will be highly appreciated.

Thanks!
