A new quest!!
After doing all this work to get the program to install properly on the ubuntu server.
Now the module does not display the configuration page.
The game is afoot!!!
I have disabled and uninstalled and reinstalled.
I have run composer dumpautoload -o.
The next thing is to investigate why the program can’t find the moduleConfig.php on the first two tries then does on the next two.
Also, I checked that mode rewrite is installed and that the webserver is configured for
<Directory /var/www>
Options Indexes FollowSymLinks
AllowOverride All
Require all granted
</Directory>
There are no obvious error messages in the error log.

SOLUTION:
I had to go back into the globals and select modules and click the save button inside modules. Then the system registered the selection of the SMS provider and showed the configuration screen.
