Can Pokemon let's go Pikachu be played with out joycon?

Can Pokemon let’s go Pikachu be played with out joycon or pokeball plus
every one cannot buy Nintendo console and controllers . So developers, is there any option for this problem?

You need to play a Switch to play legally on yuzu, but I don’t think joycons need to be connected while playing.

Then what about catching Pokemons?

I think there are plenty of online guides on how to set up the game. I don’t own the game, so I don’t know.
