Are there opensource ECoG benchmarks with train/test splits that is commonly used?

We were wondering if there is a commonly used open-source ECoG benchmark for deep learning.

While we have found lots such benchmark datasets for EEG, (SEED, TUAB, … ) with train/test splits for fair comparison of performance across papers, we could not find ones like that for ECoG.

We did find some open-source ECoG task datasets, but it seemed non of them provided train/test splits, as most deep learning benchmarks do. (e.g., Stanford ECoG dataset, Restoring Active Memory (RAM) (from UPenn))

Or could it be that there is a dataset that we are missing? Anyone’s recommendation would be greatly appreciated!
