Thank you for your support.
Since there are very few settings to configure, would it be okay if I attached some screenshots?
The first image shows the actual integration process, and the second shows the calculation to get the total cumulative count. For sending data, variable #874 is actually used.
With the settings configured exactly as shown in the images, the popup in the bottom right still showed "0/5,000,000".
If my method of sending the data is incorrect, I would greatly appreciate it if you could kindly point me in the right direction.


Also, here are the settings configured on the Steam side.
