EMR Serverless supported?

[set92]

Describe the bug
I have done the installation on a jupyter notebook with an EMR Serverless 7.7.0. But when I try to access the URL from the Spark UI, it shows a white screen with only This request is not valid. Please generate a new URL..

Environment
spark version: 3.5
platform: EMR

To Reproduce
Steps to reproduce the behavior:

1. Create EMR Serverless application.
2. Open a Notebook, and run
   %%configure -f
   {
   "conf": {
   "spark.jars.packages" : "io.dataflint:spark_2.12:0.2.9",
   "spark.plugins": "io.dataflint.spark.SparkDataflintPlugin",
   "spark.sql.maxMetadataStringLength": "1000",
   "spark.dataflint.iceberg.autoCatalogDiscovery": "true",
   }
   }
3. After running spark on another cell, you will get the link to access the Spark UI (https://spark-live-ui.emr-serverless.amazonaws.com/), which in my case takes me to https://j-00fqdv663u738h0a.dashboard.emr-serverless.us-east-1.amazonaws.com/.
4. Try to access https://j-00fqdv663u738h0a.dashboard.emr-serverless.us-east-1.amazonaws.com/dataflint will return the error mentioned.

Expected behavior
Be able to access the interface.
