How to add mods in minecraft bedrock 1.14.60?

There's a website you can download addons from: http://mcpedl.com/.

1. Choose an addon: I chose this: https://mcpedl.com/zoom-behavior/
2. Download it.
3. If it doesn't open in media fire or it downloads directly, don't download it. It may contain viruses.
4. After it downloads, open it. It will open Minecraft.
5. You will see import Started. It will say imported successfully(I already downloaded it so I will get failed)
6. Create a New world or an existing world then go to Add-Ons:
7. Choose yours and click activate. You can follow the same steps for resource packs.

I hope This helps.
