To protect the branch:

1. Select Repos > Branches in the project's main page to open the Branches.
2. Locate your branch on the page in which all branches are listed.
3. Select the ... button. Then select Branch policies or Branch security from the context menu.
4. Once you have done, select Save changes to apply your new policy configuration.
