How to increase toolbar icon size?

I looked for this on a search engine and nothing came up. The only relevant thing in advanced setting is the zoom the size which only affect the texts I type.

I can’t edit my previous post, but it seems

onlyoffice-desktopeditors --force-scale=1.25

is the only solution. It seems from here I would have to setup an alias and execute from terminal, as this can’t be applied in the settings.
