[Starfinder (Simple)] - Newbie token help

So, I am a proper newbie to roll20 since the global lockdown and have been playing Starfinder with friends using the Simple character sheets.  My question is how on earth do I get HP and SP values to appear in the bubbles above a linked token?  In D&D 5e I can do it easily but the tokens in SF are different. Apologies if this is the wrong way or place to post this.

I am such a numpty.  SO, what is not clear (or is and I didn't see it) is that the SP, HP values have to be set at GM level.  When I said I can do it in D&D 5e, I am the DM and didn't realise even though I have given players edit priviledges they can't see what I see completely. Panic over.
