In Canvas is possible to add an H5P in three different ways:
In this documentation we will be focusing on the latter two; Sub-account and Course Level. For the Account (Global) Level, you can follow these guides respectively: Setting up H5P.com in Canvas (LTI 1.1) or Setting up H5P.com in Canvas (LTI 1.3).
For both Sub-account and Course levels, when using LTI 1.1 you'll need to follow this documentation up until Part 2 Step 1. With LTI 1.3, follow this documentation until Part 2 Step 6, after that, you can continue with this tutorial.
Sub-account Level
After copying the Key and Secret or linking the Developer Key, in Canvas, click on "Admin" on the menu on the left, and select your main account.
On the new window, you should be able to see a new menu on the left, click on Sub-account, and create or select the Sub-account you'll want to add an app.
After this you will need to click on Settings in the left menu and on the top, you will see the "App" button, click on it, then on the top right corner, click on "View App Configurations", and on "+App". From now on, you can go back to following the documentation. This way the H5P tool will only be installed and possible to use on this specific course.
Course Level
After linking the Developer Key, in Canvas, go to Courses and click on a course you want to install the app.
After this you will need to click on Settings in the left menu and on the top, you will see the "App" button, click on it, then on the top right corner, click on "View App Configurations", and on "+App". From now on, you can go back to following the documentation (LTI 1.1 and LTI 1.3). This way the H5P tool will only be installed and possible to use on this specific course.
