Is there any way to customise the little loading toast that appears at the top of Plasmic pages?

In plasmic studio I see the loading state in my rich app layout, but it’s content is a spinner icon not “loading…”
So I’m a bit confused
I too had asked about customizing this message, but no answer yet: https://plasmiccommunity.slack.com/archives/C025BC1JJAX/p1701972252648229
@fmota Any luck you could shed some light on this?
I think the question here was a bit simpler than yours, so I will answer it there
