If you concentrate on making the app useful to your customers, they'll use it more often. Time that you spend repackaging it as an Electron app could be used to improve the app's functionality.
Also, many apps these days are web-based, so I'm not sure why having a shortcut in your start menu would be any "stickier" than having a bookmark in your browser's bookmark bar. A web app would be accessible from all the user's devices, not just the one it's installed on, making it more likely to be used.
And if you unnecessarily make something a desktop app when it could be a web app, you'll annoy your users by using up their disk space and RAM and wasting their time waiting for installations every time there's an update.
just do a PWA
This is my theory as well. But do remember there is more friction with getting them to install the app. Depending on your target audience, there could be issues with them installing software without getting it approved by security teams, etc.
