Error with Discovery Campaign Creation

[Hawk Scale]

Hello google ads team, i´m trying to create a discovery campaign, but generate the error:

 Error with message "The required field was not present.".
                On field: operations
                On field: create
                On field: campaign_bidding_strategy

I already tried the available bidding strategies according to the documentation, but then it generates another error for all that I tried:

Error with message "The operation is not allowed for the given context.".
                On field: operations
                On field: create
                On field: bidding_strategy

I don't know if because it's discovery you have to pass other keys, but I followed the documentation:
https://developers.google.com/google-ads/api/docs/discovery/create-campaign?hl=pt-br

help me, please
