ELECTRA for Causal LM

Hi,

Can we use ElectraForMaskedLM for causal language modeling?

It seems BertForMaskedLM was split into and BertLMHeadModel and BertForMaskedLM, one model for causal LM, one for masked LM.

Is ELECTRAā€™s Masked LM class can be applied for causal LM?
Or is there a separate class?
Or is it not possible to use ELECTRA as Causal LM in the first place?

Thank you in advance.
