How to change default filmstrip container width?

I saw that when a meeting starts, the width of the filmstrip is 140px as a default. I want to increase the size of the filmstrip width (i.e like I want to assign a minimum width for flimstrip container). In which file exactly do I have to change?

Thanks in advance

I would guess somwhere here jitsi-meet/react/features/filmstrip at ad70f12cb44b4cbf5e9f8d421c0dae08f874e1e2 · jitsi/jitsi-meet · GitHub

Hi @damencho ,
Yes it works and the exact file is reducer.js. Thanks
