Help Tracking lead booster conversion (G. analytics & tag manager)

Hi Folks,

We’re are trying to use lead booster chat as the solution for conversation on website.
However we are not being able to track conversations.
We need to track conversion after the visitor sending/answering some message or finishing the conversation.

The chat works perfectly, but without tracking conversions we are not able to measure marketing performance.

Anyone found any solution ? Any provider who could support us ?
