Installing OMV on raspberry pi 4 without using wired ethernet

1. I have access to WiFi but no wired ethernet.

2. I will buy a router with LAN ports soon. For now, I just want to set up the OMV and other plugins. I know it will be very slow as a NAS but it's okay for me.

I have a Raspberry Pi 4B. I installed the lite OS and accessed it over WiFi to ssh into it. I installed OMV using the GitHub script. It worked and OMV boots up.

I know that OMV installation removes WLAN config and I can't access the OMV without wired ethernet.

Is there any way to install OMV and supply WiFi credentials in such a way that WiFi is enabled and connected after the first boot of OMV?

Added later:

I should also mention that there is no keyboard or mouse attached to the Pi. I want it to auto-connect to the WiFi so that I can use the web interface or ssh.

Quote from Soma

Use the instructions on the GitHub but follow the "skip network configuration"

Or try to reconfigure the WiFi via raspi-config
