Jenkins declarative pipeline when condition not working

Question

I have written a declarative pipeline using shared library and I am using when condition. Even though the condition is true, the stage is getting skipped. I am unable to figure out. Am I missing something? Below is my code:

Branch Name: hotfix-poc. My branch name satisfies the condition but it still skips.

// Approve DEV Deployment
            stage('Approve Dev Deployment') {
                agent none
                when {
                    anyOf {
                        expression {
                            return (env.GIT_BRANCH.equals('master') || env.GIT_BRANCH.startsWith('hotfix-'))
                        }
                    }
                }
                steps{
                    approveDeployment(hcEnv: 'dev')
                }
            }
