Can't find "convert to glyph" / scrivener 3 for windows

On the previous version of Scrivener, I was able to select a text, right-click it and if position the mouse on FONT, a list of options appeared: Bold, Italic, Underline, Strikethrough, Conver to Glyph (or something like that)
Now, the option of Conver to Glyph doesn’t appear.
Anyone knows how can I convert selected text into a glyph?

Thank you!
