How long does sand / cement render need to dry before plastering?

Hi, I rendered a small piece of interior wall ( roughly 8 inches wide x 7 feet long), using ready-mixed mortar. There is an open window nearby, so more air for drying. The depth of the render varies between around 1/2 inch and 1/4 inch.

The idea is to install an aluminium door frame over this render, so my question is how long does the render need to dry before applying a thin coat of plaster, and then how long after that
should I wait before having the company install the door frame? Please
see photo attached. Thanks!
