When testing this, I've done the following:

1. Removed all my Kibana settings which caused it to run on a cloud context. Here are the lines I've commented out:

   # xpack.cloud.id: something
   # xpack.uptime.service.tls.certificate: config/123-client.pem
   # xpack.uptime.service.tls.key: config/123-client.key
   # xpack.uptime.service.username: <REDACTED>
   # xpack.uptime.service.password: <REDACTED>
   # xpack.uptime.service.showExperimentalLocations: false
   # xpack.uptime.service.manifestUrl: http://localhost:8081/manifest.json

2. Then, I've started a fresh Elastic Stack, deleting my old containers
3. Finally, I've checked out the latest changes in the 8.4 branch and started Kibana, connecting it to my local ES.
4. I then was still able to see the monitor management button by default.

CC @dominiqueclarke is there any other test you'd like me to do for this?

Also, please notice the snapshotted Kibana I have was also okay. It was pulled today and its tagged build date (found with docker inspect is org.label-schema.build-date": "2022-08-02T11:09:52.943Z").
