to open up the settings panel.Scroll down and select View & Manage Execution Agents in the Test Automation section.

Click on Edit

To add new tags, start typing the tag name and then select the check box and click Done.

To associate specific automated tests with tagged agents, set up the execution agent tags for the automated test in the General tab.
Good to Know!
Automated tests without tags can run on any agent regardless of agent tags.
If you select more than one tag in a test, it will look for an agent that has all the selected tags.
If you would like a test to be executed by several specific agents, make sure that each agent contains the tag selected for the test.

Click on Update entities.
Note
