If we need your team to assist in installations, what's the steps?

I'll explain step by step:

First, you register https://imbachat.com/register
You choose a service plan https://imbachat.com/en/pricing
Then you pay for your plan.
Write support@imbachat.com here with the data: your widget number
Then you pay for his services and the programmer gets to work (installs, configures, etc.)
