Problem with integration Bitbucket cloud and Jenkins using BB workspace access token

Hi All,
In Bitbucket Cloud and Jenkins integration we have faced with API rate limit issue, we were using app password but it didn’t work since the rate limit reached very quick! So the plan is breaking down the jobs into different access tokens, I created workspace access token but I don’t know how I can use it in our Jenkins jobs, for example in a freestyle I just tried to create a new credential using username/password and filled out the field as below:
'x-token-auth':'WorkspaceAccessToken'
I put x-token-auth as username and WorkspaceAccessToken as password, but in job config I get the following error:
The selected credentials do not have permission to determine whether “workspace” does or does not exist.
Any idea?
Also regarding API rate limit issue any idea is highly appreciated!
Thanks!
