When you try to upgrade to v5 this library has a breaking changes from this article https://github.com/microsoftgraph/msgraph-sdk-dotnet/blob/dev/docs/upgrade-to-v5.md

The first step you need to get token like this

var interactiveBrowserCredential = new InteractiveBrowserCredential(interactiveBrowserCredentialOptions);
var graphServiceClient = new GraphServiceClient(interactiveBrowserCredential);

or like custom authentication flows can be done creating an implementation of IAccessTokenProvider

public class TokenProvider : IAccessTokenProvider
{
    public Task<string> GetAuthorizationTokenAsync(Uri uri, Dictionary<string, object> additionalAuthenticationContext = default,
        CancellationToken cancellationToken = default)
    {
        var token = "token";
        // get the token and return it in your own way
        return Task.FromResult(token);
    }

    public AllowedHostsValidator AllowedHostsValidator { get; }
}

Creating instance of GraphServiceClientCreating

var authenticationProvider = new BaseBearerTokenAuthenticationProvider(new YourAuthenticationProvider()); // Authorization method
var graphClient = new GraphServiceClient(authenticationProvider); 

Insert your licences for removing and adding. Make sure that this data has value in licensesToRemove or licensesToAdd

var licensesToRemove = new List<Guid?> { };
var license = new AssignedLicense { SkuId = "yourLicenceId" };
List<AssignedLicense> licensesToAdd = new List<AssignedLicense> { license };

Make query

await graphClient.Users["yourUserId"].AssignLicense.PostAsync(new Microsoft.Graph.Users.Item.AssignLicense.AssignLicensePostRequestBody()
    {
        RemoveLicenses = licensesToRemove,
        AddLicenses = licensesToAdd
    });
