Incorrect Loki Documentation for updating configurable parameter

As per the documentation[0],

[0] https://docs.openshift.com/rosa/logging/cluster-logging-loki.html#cluser-logging-troubleshooting-loki-entry-out-of-order-messages_cluster-logging-loki

To modify the below parameters, we have to edit the file `loki.yaml` but there is no such file as `loki.yaml` since the lokistack is operator managed, we need to edit the file using `oc edit lokistack`, there are no clear example on where and how to add these parameters in lokistack

grpc_server_max_recv_msg_size: 8388608
chunk_target_size: 8388608
ingestion_rate_mb: 8
ingestion_burst_size_mb: 16

For the Demo, I have updated the lokistack as below

oc edit lokistack

...
...
  spec:
    limits:
      global:
        ingestion:
          ingestionBurstSize: XX ---> Whatever is the number needed
          ingestionRate: X ---> Whatever is the number needed
    managementState: Managed
...
...

what are the other parameters that can be configured using the `Lokistack` do we have a list of that parameters

For the below parameter, Are these to be configured with Lokistack

• grpc_server_max_recv_msg_size: 8388608

• chunk_target_size: 8388608
