Graph API for User fetch

Question

I have an Azure AD B2C Tenant which I have configured with an external identity provider. In the identity provider configuration, I have mapped 'User ID' field with an attribute 'subject' from the claims.
Now, I am trying to use Microsoft Graph API to fetch users from my B2C tenant using this 'User ID' field. I am able to fetch users basis their name / displayName and similar attributes. However, I need to do it using 'User ID' field.
Is there a way to achieve this ?

I have tried the below method for fetching users using name and it works fine, however need correct attribute name to be used in the filter for the 'User ID' field -

this.graphClient.Users.Request().Filter($"startsWith(displayName, '{nameValue}')")
.Select(e => new
{
e.DisplayName,
e.Id,
e.Identities,
e.UserPrincipalName
})
.GetAsync();

Is it because I have tried to use 'User Flow' in this scenario for my sign-in? Is this possible to do using 'Custom Policy' ?

Awaiting responses. Thanks in advance.

Hi @Anand Patil

Do you want to filter users by user id? Please try the following code snippet:

this.graphClient.Users.Request().Filter($"id eq '{id value}'")  
.Select(e => new  
{  
e.DisplayName,  
e.Id,  
e.Identities,  
e.UserPrincipalName  
})  
.GetAsync();
