Measure to count clients

Hi there,

Following is my sample dataset:

I want to create a measure to know 'amongst people who are still in their first 3 months from signup date (that is people who signed up from 22/04/2022 onwards), count of people who made a payment since then, split across relevant months'.

For example : client_id 2 falls in this measure & made a payment in Apr, May, Jun & Jul and is counted in months from Aprl to Jul.

So, the measure result for the above dataset is like this:

Here is my sample pbi file: https://1drv.ms/u/s!Ag919_pO_UKrghcn8byYZRmTO2TS?e=INaTZr

Many thanks for your help!
