How to run nuget package (tool) from artifact feed - azure-devops

Question

I'm begginer to devops. And I got a task to create 2 pipelines. One for building project and publishing it to artifact feed. And another pipeline is to run that tool.
First one I have created (created nuget as a tool and placed in my feed).
How can I now create pipeline that will do dotnet run but from my feed?
I just need guidance a big picture.
I'm trying something like this:
pool:
vmImage: windows-latest
jobs:
- job: RunTool
displayName: Run Tool
steps:
- task: DotNetCoreCLI#2
inputs:
command: 'custom'
custom: 'tool'
arguments: 'install -g --add-source=https://pkgs.dev.azure.com/EPMC-STC/ab5c31ad-1d77-4369-80f4-ff2f14a12667/_packaging/MilanDjukicFeed/nuget/v3/index.json MigrationApp --version 8.0.18'
I'm getting:
Installed an ASP.NET Core HTTPS development certificate.
To trust the certificate run 'dotnet dev-certs https --trust' (Windows and macOS only).

The tool package could not be restored.
Tool 'migrationapp' failed to install. This failure may have been caused by:
* You are attempting to install a preview release and did not use the --version option to specify the version.
* A package by this name was found, but it was not a .NET tool.
* The required NuGet feed cannot be accessed, perhaps because of an Internet connection problem.
* You mistyped the name of the tool.

On Artifacts I have MigrationApp nuget package. I can download it and run it localy.

Since you are creating Nuget as tool and need to use it in pipeline, you can use dotnet tool install command to install the Nuget tool and define the feed source.
For example: Add a command line task/ Bash task/ PowerShell
dotnet tool install -g --add-source=https://pkgs.dev.azure.com/<org-name>/<projectname>/_packaging/<feedname>/nuget/v3/index.json toolname
Then you can use the nuget tool in next tasks.
On the other hand, if you need to download the Nuget Package, you can use the task: Download package task to download the nuget package from feed and do next actions.
