This Process is very simple, let’s do it together:
In the left side menu, look for the module called: Publish and click on it.
At the bottom left of the text box to write your post you will find a button called Hashtags. Click on it.
A drop-down list will appear. Choose and click on the name of the hashtags group you have already created (If you don’t know how to create one, you can read our article Create a Hashtags Group).
