Angular 11 - plotly-plot' is not a known element

I followed the getting started steps provided in the documentation but I am not able to run Plotly successfully

npm version: 6.14.6
node version: 12.18.1
Angular cli version: 11.2.14

I get the following error when I add <plotly-plot> element to my template

plotly-plot' is not a known element:

I have tried the following

1. Used the CDN version
2. https://github.com/plotly/angular-plotly.js/issues/155

Did I miss something?

从 getting-started 文档开始，使用 Angular CLI 11.2.14、Node 12.18.1 和 npm 6.14.6 重现所报告的设置。将 CDN 尝试与 issue 155 中讨论的设置进行比较；完成的标准是确定 被拒绝的原因，并记录或修复该设置，使示例能够运行。
