Python Azure时间触发函数部署后不显示且执行失败求助

我使用Python 3.11.9在Visual Studio Code中编写了一个时间触发型Azure Function，本地通过F5启动运行正常。但通过VS Code部署至Azure Portal时，尽管部署输出和Azure标签页均显示“部署成功”，Azure门户的Function App概览页面却看不到该时间触发函数，仅能在函数目录下看到应用文件。我尝试了三种部署方式：Azure标签页的本地工作区部署、Azure标签页的资源部署、终端命令部署，均未解决该问题。

已修复：函数显示问题 #

添加Ikhtesam回答中的额外依赖后，函数已能正常显示在Azure门户中，但新的执行问题出现：

函数按配置每5分钟尝试运行一次，但每次执行均失败。调用追踪显示为权限问题，日志提示访问Key Vault被拒绝。我使用DefaultAzureCredential和SecretClient获取Key Vault中的密钥，Key Vault采用RBAC权限模型，且Function App的服务主体已被分配相关角色，但仍出现访问被拒绝的情况。
