Note: I recognized that this only works for shares where the credentials how not been saved. For shares where you have saved the credentials instead your current logged-in user-account is shown. Therefore for connections using saved connections you have to check Windows Credential Manager what username is used for establishing the connection.

You can use the PowerShell command Get-SmbConnection (local admin permissions required).

I have tested this command on a Windows 10 client and it shows all my network connections similar like the following sample output:

PS C:\>Get-SmbConnection
