@smlambert could you grant Anna access to Adoptium Grinder? She needs to run some PR testing. Thanks

[smlambert]

@annaibm - you should see a GitHub invitation to a test-triage team, once you accept it, you will have access to run Grinder jobs at ci-adoptium.net

[annaibm]

@ShelleyLambert I have received the invitation and accepted it. I could run the Grinder job. Thanks!
