Amazon Athena connection with Power BI Service

Hi, i have some data at AWS S3 and already connect the data to my Power BI Desktop using ODBC and some report has been createed. However, when i publish the report to Power BI Service, the data cannot refresh in the Power BI Service.

Then i read some articles, i know i need to install a PBI Gateway in order to update the data. My company already setup the PBI Gateway with version March, 2021, and i try to add the AWS Athena as data source using ODBC. In the "Manage connections and gateways" tab, it show the data is "online" in status; and the ODBC configuration also show that the test connection is "Successfully connected".

But when i refresh the dataset in PBI Service, data source error report that "Unable to refresh the model because it references an unsupported data source". 

i have some questions confusing:
1. i have set the "import" at Power BI Desktop, is it the reason for unsupported data source??
2. when i go the PBI Service "setting" - "Datasets" tab, i find the datasets with no option on "Gateway connections", it said that data is using custom data connector. so i cant map the dataset to gateway. Then should i do something on the PBI Gateway - custom data connect ??
3. is PBI services support ODBC connection with Athena like PBI desktop ??
