How to change the caption in material-ui menu?

Question

css

Hey! I added a menu from https://material-ui.com but I can't figure out how to change the inscription in it. So that there is no Open menu, but just a menu.

<div className="contNav-mobile">
          <Button aria-owns={anchorEl
              ? 'simple-menu'
              : undefined} aria-haspopup="true" onClick={this.handleClick}>
            Open Menu
          </Button>
          <Menu id="simple-menu" anchorEl={anchorEl} open={Boolean(anchorEl)} onClose={this.handleClose}>
            <MenuItem onClick={this.handleClose}>О Комплексе</MenuItem>
            <MenuItem onClick={this.handleClose}>Преимущества</MenuItem>
            <MenuItem onClick={this.handleClose}>Цены</MenuItem>
            <MenuItem onClick={this.handleClose}>Рассрочка</MenuItem>
            <MenuItem onClick={this.handleClose}>Планировки</MenuItem>
            <MenuItem onClick={this.handleClose}>Контакты</MenuItem>
          </Menu>
        </div>

What it looks like now
