In OJS 3.4.0.8, some tools are missing

In OJS 3.4.0.8, some tools are needed in some sections, such as the following:

Settings>Journal
Key Information


Settings>Website>Announcements

Settings>Workflow>Author guidance

Image and HTML tools are missing

The Text Editor Extras plugin, available from the plugin gallery, helps you to enable these tools.

I have version 1.0.0.5 installed. Can you guide me to install version 1.0.1.0?

Solved:
I downloaded the .zip code file from (GitHub - pkp/textEditorExtras: An OJS plugin to add controls to the rich text editor to upload images, manipulate the HTML code, and add tables.).

I uploaded this file via cPanel to the public_html/plugins/generic/ directory.

I unzipped it and renamed it to: textEditorExtras.

Then in the journal Website Settings > installed plugins, you can configure the tools for different modules
