What CRM or other script to use for technical support in VK?

Question

CRM

Hello. There is a certain Vkontakte group that has n number of subscribers and n number of messages are sent to its messages every day. It is required to display all these messages in a separate crm or any other script
(it is important that the script or crm can be deployed on your server). So, what service can be used for such purposes. Approximate number of support agents - 30
