I am learning that the modern experience of SharePoint Online does not leave much room for customization. I had a request from the line of business to make the filter ICON considerably more visible for some of their novice users. I know with the modern experience within a document library the default location is to the right of library designated by the filter icon. I was asked to make it more obvious and basically boldly in the users face when a user opens the library. I have been looking for a setting that would allow me to make such a customization to no avail. Does anyone know of a way to do this if at all using the Modern Experience?
You need to inject JS file using SPFx extension.
Code required to change properties of filter icon
$("button[name='Filters pane'] i").style = "font-size:22px;font-weight:bold";
