Perspective icon question

Good morning guys, I’m very new about perspective and I’m playing with icons.
I’m sure I wrong something, but I don’t understand why some icons of google material symbols work and other don’t.

For example if I set as path of the icon on perspective “material/settings_suggest” nothing is showed (Material Symbols and Icons - Google Fonts)

Thanks for the help

On Windows the icons seem to be stored in
C:\Program Files\Inductive Automation\Ignition\data\modules\com.inductiveautomation.perspective\icons\material.svg

I opened mine in Notepad++ and there is no reference to settngs_suggest so I’d say it’s not there.

Ok, I thought that all the symbols in the link could be found in perspective. Should be possible to add this icons for example in my project icons?

See if Material Icons Guide  |  Google Fonts  |  Google Developers helps. I’m just reading through it now. It may be possible to update your material.svg or to link to Google Fonts.

What version of Ignition are you on? It may get updated on version upgrade.

Thanks for the link, I read it as soon as I can.
Actually I’m using Ignition 8.1.6.
