Welcome to the forum.
Have you actually requested an appeal?
To be placed in the Support Group you will need to meet at least one of the SG Descriptors, these are listed in the ESA Claim guide on the following link.
www.benefitsandwork.co.uk/help-for-claimants/esa1 Have yo discussed this with your CAB advisor?
Who is producing your submission for the hearing?
Have you received the DWP evidence bundle yet?
If you can provide us with more information by replying to this post then we will do our best to help.
