I believe so as well. Compose is very similar to Electron. Jetbrains Toolbox (which uses compose) uses 500mb memory which is on par with what Electron would use for such a simple app.
I already ditched the Toolbox app on macOS, because it marks the binaries as Intel only (while they're universal). The IDE's built in updater seems fine if you're only using the stable versions. So I think I'm just going to remove the Toolbox app from all my machines.
