This macro renders it's content only if current user is in the configured security group
Code is really simple and goes like this
## @param SecurityGroup:title=Security group|type=string|required=true|desc=Security group to check for membership
#if(${action.authenticatedUser} && ${userAccessor.hasMembership(${paramSecurityGroup}, ${action.authenticatedUser.name})})
${body}
#end
Complete macro configuration looks like this
Example usage
The info block with the message "Hello, you are in the group" will be shown only to the users who are in "confluence-administrators" group
