There was a problem hiding this comment.
next time if any please don't change this file in PRs, since it is a source of conflicts (compiled file)

@fsahmad thanks for contribution. please consider fixing types for typescript users |
I added the new fields to the index.d.ts file already in this PR, is there any other place typings are defined? |
nice, thanks! |
