My expedite was accepeted, but no time frame was given

I received this email:
On February 16, 2022, we approved your request for expedite processing on your Form I-765, Application for Employment Authorization, Receipt Number XXXXXXX. We are processing your case and will send you a notice of action with our final decision.

However, they did not mention that within 45 days I should get a decision. What does this mean? Will there be another email from them?
