Order that's from Grindr? (7)

I believe the answer is:

mandate

I'm a little stuck... Click here to teach me more about this clue!

'order' is the definition.
(I know that mandate is a more specific form of the action order)

I don't understand the rest of the clue.

Can you help me to learn more?

(Other definitions for mandate that I've seen before include "Authorisation to a politician" , "Social appointment for male - or authority given" , "Authority given by electorate" , "Order - charge" , "Authority to do something" .)

I've seen this clue in The Independent.
