How to enable users to automatically become promoters after purchasing products?

Currently, on the premise that merchants have enabled recruitment, users will automatically become promoters upon purchase when the following conditions are met:

1. Set the joining condition to "Conditional" and select either "Purchase any product in the store" or "Purchase specified products".

2. Disable application information and recruitment review.

3. The order for the corresponding product purchased by the user is not a free order.

Note: If recruitment is enabled for multiple groups, ensure that the joining conditions for other groups are different (i.e., do not select the same specified product or "Purchase any product in the store" as the joining condition).
