Using UMG Buttons as touch control?

I need to make simple touch buttons on the left and right side of screen. Can I use UMG, create buttons in the UI Blueprint and somehow force character to move left and right, when these buttons are pressed? Without using other input, like joysticks?

My problem is - I don’t need to use virtual joysticks to control character, and in Input Settings I see no choose between joystick and button.
