How to detect device RAM to avoid black textures on low-memory devices

How do I...?
1

I’m developing a game in GDevelop and I’ve noticed that on devices with less than 4 GB of RAM, some large textures turn black instead of displaying correctly.

I’d like to detect when the device has low memory and load lower-resolution textures in those cases.

Is there any way in GDevelop (or using JavaScript) to detect the device’s RAM amount or available memory?
Alternatively, is there another reliable method to detect when the device can’t handle high-resolution textures?

Thanks.
