How to share Windows 10 host drive with Windows 7 guest

Provided Windows 7 Ultimate SP1, Gen 1 as guest VM and Windows 10 Pro 20H2 as host, how do I share host data-only drive G: with guest VM?

Enhanced session mode can’t be enabled, as Windows 7 does not meet all of the minimum requirements as guest VM.
Ping is functional both ways.
Mounting host drive using Windows explorer isn't possible as host Domain(or IPv4 number)\user isn't recognized.
