Picker with a large number of items

Hello,
I’m new to the community, and I’m looking for help to have a Picker with the complete list of countries without having to make a query to the Cloud Database.

If I run a query to the cloud database and then a modify control, I can load the list in the picker items, but due to the nature of the app, this would generate far too many queries, increasing the costs…

I have searched the documentation and videos on Youtube, but I can not find how to have a Picker with many items locally because if I try to include the entire list in the Option Value of the Picker, it reaches the middle of the list, around the letter M…

I would be grateful if you could enlighten me on how I could achieve my goal.
Regards!
Eduardo
