How to reduce WhatsApp Desktop App RAM Usage?

My problem is with WhatsApp itself. I know that modern browsing is RAM intensive (specially webapps built with Electron), but we close and open tabs all the time, which compensates for the RAM usage. But, for instance, my WhatsApp Desktop App (a glorified browser tab) is open **ALL** the time since it is a major work and personal tool for my digital life, and sacrificing 1GB of RAM for a communication application seems like overkill to me. It consumes around 600MB to 1GB depending on its usage. WhatsApp Renderer GPU is the most RAM intensive task. I created an Automator App that runs this terminal command (I saw it here ): open /Applications/WhatsApp.app/ --args --disable-gpu But it stills open WhatsApp with the GPU renderer. I would like to ask what could I do to force WhatsApp to be less RAM intensive or how to I stop making it use my GPU (since the terminal command above did not work).
