The campaign I participated in is not shown.

This is because after the campaign period, the advertiser will check the post and approve it, but the approval has not been given. After the advertiser approves the post, the reward will be paid at the end of the following month.

Advertisers will approve the post after the campaign period is over, not after posting. If the campaign period is long, it may take 1~2 months from submission to payment.
