Use Anycast, Roku or other casting device that supports Miracast (Windows/Android) and Airplay (Mac/iOS) added to the HDMI port.
Once you have your projector, before setting it up, connect it to the computer/device you will be projecting from.
“Mirroring screen” is also called “Duplicate”, or screen sharing, and allows projector to show what is displayed on your computer/or device screen. Then you can open patterns on your computer or device and they will also show up in the projected image.
Connecting projector wireless to device/computer via other casting devices
(Firestick, Roku, Anycast, Apple TV, etc.)
First see this post to understand which casting device will work with which devices:

iPhone and iPad will need Apple TV or Roku casting device, or any other casting device that has AirPlay. Firestick does not have Airplay.
Plug the casting device’s HDMI cable to the HDMI port of the projector. Casting device will need to be plugged in for power, if it has a usb cable plug that into USB port of projector and it will get power from projector.
Then follow instructions for the specific casting device on how to screen mirror with it
