How to configure Bitbucket Build Status Notifier Jenkins plugin to connect to BitBucket Cloud for Jenkins Pipeline projects

Question

I would like to know how to configure Bitbucket Build Status Notifier Jenkins plugin to connect to BitBucket Cloud for Pipeline projects.

Basic instructions are here, on a plugin homepage: https://plugins.jenkins.io/bitbucket-build-status-notifier/

However, following those instructions yield successful call from Jenkins like:

Sending build status INPROGRESS for commit dd4535c01718552b76d6e7f9568ad89bf2dd860b to BitBucket is done!

But on BitBucket Clould side there is no effect whatsoever.

I have tried basic call from documentation:

bitbucketStatusNotify(buildState: 'INPROGRESS')

No effect.

Then I have tried, based on this site answer (Why does the Jenkins bitbucket-build-status-notifier-plugin post the status to the shared pipeline library repository?):

  bitbucketStatusNotify(
           buildState: 'INPROGRESS',
           repoSlug: 'repoSlug aka repositoryName, e.g. some-app',
           commitId: env.GIT_COMMIT
  )

Again, no effect.

Then I have tried something on my own (various variants of this):

   bitbucketStatusNotify(
     buildState: 'INPROGRESS',
     buildDescription: "${env.JOB_NAME}",
     buildKey: "${env.BUILD_NUMBER}",
     buildName: "${env.JOB_BASE_NAME}",
     repoSlug: "my-repo-name",//BitBucket Cloud repo name (last part of repo url)
     commitId: env.GIT_COMMIT    
   )

And again no effect. I think there is something with data. So if I would sent "the right" data would be OK? Can someone tell me what I am doing wrong? What BitBucket Cloud API expects to get?
