Full screen with video tag

In a meteor project, I use the “video” tag of HTML that I control with javascript.
In this tag, I do not specify the ‘controls’ attribute, which allows me to create my own buttons and have full control of this tag. A button allows me to switch to full screen.
But, in full screen, the default control bar of the video tag appears although I did not specify the attribute ‘controls’ in this tag.
Has anyone ever had this problem, and how to solve it ??
Thank you for your answers.
