$core_v2_conversation.Create not working for normal user after 12.x upgrade

Hi Team,

Here is one scenario where $core_v2_conversation.Create is not working:

I am logged in as a normal user and I am a UG Leader of a group, when I am trying to send message to all the event attendees it's not working but it is working when I am logged in as administrator.

It was working fine older version i.e. 10.x but after upgrade to 12.x it is not working neither throwing any error.

An early resolution is something I am looking for.

Here is the code :

#set($admin_contact_body = $core_v2_page.GetFormValue('body'))
#set($admin_msg_body = $core_v2_ui.FormatHtmlAsText($admin_contact_body))
#set($admin_usernames = $core_v2_page.GetFormValue('usernames'))
#set($admin_conversationResponse = $core_v2_conversation.Create($admin_msg_body, $admin_usernames))
