Where is “campaign_product_source”

[HongruiJackson]

In v1.3, your team added a new request parameter "campaign_product_source"，which will effect the campaign level minimum budget (https://business-api.tiktok.com/portal/docs?id=1739381246298114). It seems that this parameter not in the java class "CampaignCreateBody". So how can I set my budget correctly? Thanks.
