How to run 'dotnet dev-certs https --trust'?

I'm new in ASP.NET.

Environment:

• Ubuntu 18.04

• Visual Studio Code

• .NET SDK 2.2.105

I'm in trouble with some command running.

I was reading tutorial at

https://learn.microsoft.com/ja-jp/aspnet/core/tutorials/razor-pages/razor-pages-start?view=aspnetcore-2.2&tabs=visual-studio-code

and ran this command:

dotnet dev-certs https --trust

I expect https://localhost should be trusted.but I found the error message;

$ Specify --help for a list of available options and commands.

It seems that the command "dotnet dev-certs https" has no --trust options.How to resolve this problem?
