How to change resolution with a script from ultrawide to "regular" resolution? (ex. 1440) on a MacBook Pro

I am using an UltraWide monitor while working from home. But when I'm screen sharing, it's a weird view for the others so I am hoping to find a quick way to change my resolution to black bars on the sides and give me a more 'normal' resolution. Is there any app/script that can help me achieve this?
