How to provide the lookup entities in .txt format

@JiteshGaikwad Thank you. I have tried that, But still it is not getting recognised. How to provide in NLU.md file like:

intent: greet

  • Hi, I am [Rakesh] (name)

lookup: name

./names.txt

so when I type Hi, I am santhosh. santhosh should be entity right. but not recognising santhosh as entity even if it is in names.txt file I have also tried names.txt instead of ./names.txt which basically I shouldnot But tried.
