Invite user to group

[williamn]

Hello,

I learn that this wrapper does not support Invite user to group. Any plan to add the functionality in near future?

Thanks!

Hi,

No plan in the near future, but this library is pretty much community driven, so PRs are more than welcome (awthanks).

@rberrelleza please review my commit. If it is a good to go, I will create a PR. Thanks

Looks good, thank for the contribution! Could you add a use case for inviting a user that already exists on the group?
