Looking for help with the -Q switch for Search-MgDrive

[pgbfnf]

Hello folks,
I'm very new to Graph, so I hope I'm not being too obtuse here

I'm trying to convert this API call to the equivalent Powershell Mg command:
GET https://graph.microsoft.com/v1.0/drives/{drive id}/root/search(q='proposed_vm_decoms')

I'm fairly certain the command equivalent is something like this:
Search-MgDrive -driveid "{drive id}" -Q q='proposed_vm_decoms'

However, when I attempt this, or any variation, I get errors such as the following:
Search-MgDrive_Search: General exception while processing

I'm using Microsoft.Graph 1.25.0 Powershell module.

My end goal is to find the ID for a file to download, since I'm not aware of way to download a file using only the file name. (Get-MgDriveItemContent seems to require a file ID)

Thanks.

UPDATE - same behavior with 2.0.0-preview8
Is this a bug perhaps?

I'm going to submit a bug, so perhaps this discussion is moot at this point.
