Any cheap phone screen stylus with a soft tip, about €1.50 here in local shops. Avoid disks (awkward and easily broken) or fine tips (those are for higher resolution touch resistive screens).
The Aura One is ordinary capacitive touch.
The Staedtler is for a Wacom EMR type digitiser. It might not work.
Avoid
Disc tips
interchangeable tips
Fine Tips
Any item compatible with Apple Pencil, EMR, Wacom, Surface 3 or later Pen (i.e. anything with pressure sensing).
Only get simple soft rounded tip no less than 3mm (1/8″) diameter.
Edit:
This is like the one sold locally.

Works on all phones, tablets, Kindles, Kobos* I have tried. Soft tip doesn't wear screen.
Doesn't work on old Palm PDA or old Nintendo as those are resistive so need a pointy plastic or bamboo stick.
[* You have to press a little more on older ereaders, like original Kobo H2O that use IR light instead of capacitive, to block the light. Oddly works fine on the Sony PRS-350.]
