Description

https://github.com/phaserjs/phaser/blob/master/src/textures/DynamicTexture.js#L761-L763

     * You can pass in a string in which case it will look for a texture in the Texture
     * Manager matching that string, and draw the base frame. If you need to specify
     * exactly which frame to draw then use the method `drawFrame` instead.

But drawFrame method is not existed (removed already) in DynamicTexture class in phaser4.
