Hi @Rammy1957 ,
Do you want to create a QR code so that people could scan this QR code to open your canvas app?
If you want to create a QR code for other users (in your Org) to scan it to open your app, I think the Google Chart API could achieve your needs.
Please check and see if the following article would help in your scenario:

https://developers.google.com/chart/infographics/docs/qr_codes
I have made a test on my side, please check the following workaround:
Add a Image control within an app, set the Image property to following:
"https://chart.googleapis.com/chart?cht=qr&chs=100x100&chl=https://web.powerapps.com/apps/5374afc0-b460-4121-866a-2829402a0061?tenantId=xxxxxxxx-f6a5-xxxx-89a9-xxxxx9d6c706"
Note: The 'https://web.powerapps.com/apps/5374afc0-b460-4121-866a-2829402a0061?tenantId=xxxxxxxx-f6a5-xxxx-89a9-xxxxx9d6c706' represents the Web URL of your Register canvas app.
You could get the Web URL of your Register canvas app as below:
After that, the end users in your Org could scan above generated QR Code to open your app.
If you want the external users (outside your Org) could scan the QR Code to open your app, I afraid that there is no direct way to achieve your needs. Currenly, we could not share canvas app with external users.
As an alternative solution, I think the PowerApps Portal functionality could achieve your needs. You could consider create a PowerApps portal on your side, then embed your Register canvas app within it, then assign access permission of this Portal to these exernal users, after that, these external users could be able to access the embedded canvas app through the Portal.
More details about PowerApps Portal, please check the following blog:
