I have idle3 installed but get a "Command 'idle3' not found" error when I try to invoke it

I am using Ubuntu 18.04.2 LTS and have Python 3.6.7 installed.

I installed idle3 using the following command:

sudo apt-get install idle3

which successfully installed the ide.

However, when I try to invoke it using idle3, I get the following error:

Command 'idle3' not found, did you mean: command 'idle' from deb idle
Try: sudo apt install <deb name>

If I run sudo apt-get install idle3 again, I get the following message:

Reading package lists... Done
Building dependency tree
Reading state information... Done
idle3 is already the newest version (3.6.7-1~18.04).
0 upgraded, 0 newly installed, 0 to remove and 10 not upgraded.

The command which idle3 produces nothing. What am I doing wrong and how do I get idle3, which is presumably installed on my system, to run.

The default Python in Ubuntu 18.04 is Python 3.6.7. Typing the command idle in the terminal starts IDLE (using Python 3.6.7). You can also start idle and idle3 by clicking on their icons in the Dash.
