Rfe on h4 ead while H4 extension is pending

Need help on RFE response on h4ead:

I received rfe on h4ead and was told to submit approved h4 status.I have applied for h4 extension on feb 2020 but no approval yet. Biometrics done already.

Note:This ead was associated with an earlier h4 and that h4 was valid only till june 2020.So,when I raised service request after the processing time passed ,they gave rfe for approved h4.

What documents can i submit to respond to the rfe?Anyone on the same boat please help.
I have approbed h1 of spouse and receipt notice of h4 .

You can send the pending H4 Extension receipt copy.

Will that work?They have asked for appproved i797 for i539.
