How to retrieve a list of entities without specifying rowKey from Azure Table Storage in the TableOperation?

As described here, is seems like there is no method for querying group of entities from azure table storage given only the partitionKey. https://docs.microsoft.com/en-us/dotnet/api/microsoft.azure.cosmos.table.tableoperation.retrieve?view=azure-dotnet

I have several groups of partitionsKeys, with different rowKeys. But i want to query all entities just providing the partitionKey.

How can this be done? Is there no way to do this using Microsoft.Azure.Cosmos.Table ? My rowKey values are not incremental/structured, but unique... Thanks

Update: Syntaks:

public async Task<T>> RetrieveEntitysAsync<T>(string paritionKey) where T : TableEntity, new()
{
    TableQuery<MyDataEntity> query = new TableQuery<MyDataEntity>()
        .Where(
            TableQuery.GenerateFilterCondition("PartitionKey", QueryComparisons.Equal, "myPartition")
            );


    await CloudTable.ExecuteQuery(query);

}
