Withdraw money from OPC

Hello,

I am sole director in an OPC, which is engaged in export of software services. I haven't withdrawan any salary till now. I have a few contractors who raise bill to company and save tax using 44ADA, can I also raise an invoice to my company for technical services that I provide to the company? (I know for director services GST has to be paid on RCM basis, hence the distinction for both kinds of work)

Or is withdrawing it as salary my only option?

Thanks
