In member Task<IdentityResult> MartenUserStore.CreateAsync(UserDocument user, CancellationToken ct), change parameter name ct to cancellationToken in order to match the identifier as it has been declared in Task<IdentityResult> IUserStore<UserDocument>.CreateAsync(UserDocument user, CancellationToken cancellationToken) (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1725)

Change return type of method 'NormalizeEmails' from 'System.Collections.Generic.IReadOnlyList<string>' to 'System.Collections.Generic.List<string>' for improved performance (https://learn.microsoft.com/dotnet/fundamentals/code-analysis/quality-rules/ca1859)

The behavior of 'string.ToLower()' could vary based on the current user's locale settings. Replace this call in 'GroupEndpoints.TestScript(GroupScriptTestRequest, IGroupMembershipEvaluator, IDocumentStore)' with a call to 'string.ToLower(CultureInfo)'.
