yeah, no, it's just a selection between male, female, and nonbinary. nothing as complex as custom pronouns.
honestly, it kinda ticks me off, the way those options are written, too. like, it should be masculine, feminine, and neutral, if it isn't just changed to let you type in whatever pronouns you want. pronouns and gender aren't the same thing, and "nonbinary" is an umbrella, not a single identity. though, I guess I'm rambling a bit too much about this, lol.
