Scaling player down in runtime?

Hi, for a project of mine i want to scale my player to be insect size it’s kinda the same problem as this topic:

but iam not using VR i want just regular third person blueprint. can someone please tell me how to do this?
would be nice to be able to scale in runtime with the push of a button.

thanks in advance!

is it smarter to scale the envoirment up or is scaling the player down also a good idea?
