is there any specific permssion in Azure devops for code review?

i want to give a person a permission for code review purpose only (no other permission).Is there any such permission in Azure DevOps? Anyone please help !

There is no such permission in Azure Devops. The only option is to limit the person permission as much as possible, which is denying all the other permissions and only allow contribute to pull requests. You can check out below steps:

1, Add user to your organization with basic access.

Go to Organization settings->Security->Permission->Users->Select the user and deny All his permission.

2,Add this user to the Readers group of your Project

Go to the project settings->Permissions->Select Readers group->Add this user

3,Set the user's permissions for your Project.

Go to the project settings->Permissions->Users->Select this user-> Deny all the permissions except View project-level information.

4, Setting user's permissions for Repos.

Go to the project settings->Repos->Repositories->Select the repo(Or Click the Permissions tab under All Repositories to set the permissions for all repos)->Permissions->Search for the user in the search bar->Only allow Contribute to pull requests and Read permissions for this user

5, Set permissions for Pipeline.

Go your project portal->Pipelines->Click the 3dots->Manager Security

Search for the User in the Search bar->change his permission of view builds and view build pipeline to Deny

6,Set permission for Release.

Go your project portal->Releases-> Click the 3dots->Security

Search for the User in the Search bar->change his permission of view releases and view release pipeline to Deny

Even so the personal's permission cannot be limited to only review code entirely. He can have the read permission to Overview and Artifacts.

Hope above helps!
