ClickSend SMS to RG phone list

Hello All,

So i ran into this issue where i was trying to use a RG group with a phone number and using clicksend sms to send to all users in the RG group. However Clicksend support says they only support one sms message at a time. So i’ve been trying to use a backend workflow to accomplish this but seem to be still running into the same issue. I apparently have something wrong. Has anyone been able to do this successfully.
