Adding a splash screen by default?

[SylvainBigonneau]

I noticed that, contrary to my PWA behavior, my TWA app (built with this module) does not display a splash screen at startup.

It seems to be generic for PWAs, but maybe in the case of TWAs it has to be programmed into the app itself ?

There seems to be a how-to here that I might follow.

I don't know if it qualifies as "expected behavior", in the sense that I expect my TWA experience to be roughly identical to my PWA one, so I just wish to open that conversation.
