Pollination of cherry tree

I've bought a cherry 🍒 tree- 'Hedelfinger' it's not a self pollinator (didn't realise this) 
Will pollinate with an established cherry ?

From one supplier:-

It is not self-fertile and needs a pollination partner:
Morello, Stella, Sunburst

So it looks like you need a pollination group 4 cherry to accompany your Hedelfinger.
