Steam Group Auto Inviter

I need a program that automatically invites people from Steam groups or from my 'Recently played with" section to my own steam group. Steam released an update a few months ago that restricts group invites to only your friends list. I need a way around this if anyone has any ideas.

Hope someone can help me

Im also looking for a steam group invite bot or something similar to the one you can buy, but i would love if there was one for a cheaper price/free
