left mouse button and rear side button

The reason I ask you this question is that I would like to know if with the Razer Deathadder V2 Mini I can hold the left mouse button and press the rear side-button and it is detected? (the left click is maintained throughout the action). That is, once I have pressed the left mouse button and press the rear side button, will the side-button click be detected? (the left mouse button is held down throughout the action). The mice I used before worked with this combination of buttons. This combination of buttons I use a lot in for example "Fortnite". So for me it is very important to knoz before I buy this mouse. Thanks
