I cant acces functions of a base class - c++

Question

Currently, I am learning c++ and just for fun, I wanted to code a little chess game (without an AI of course). I use visual studio community aside and SFML 2.5 as a renderer and for graphical objects. I tried to make a model called "figure" for all figures. So I have a figure class that inherits from sfml sprite (a drawable) and a pawn class f.e. that inherits from the figure. Sf:: sprite -> figure-> pawn/queen/tower etc... but for some reason, I can't use the pawn as a sprite, for example, I can't draw it with the draw function of my windowRenderer.
But the function documentation says it requires a drawable object. I get an error message that says something like: the conversation in the base class that is not accessible is not valid. Have I done something wrong or is it not possible to use a sprite like this. Here are my constructors because I think I its most likely I made an error there. I have only coded in java so far so the separation into header and implementation file is a little foreign for me also the constructor syntax is different.
figure.h:
class figure : sf::Sprite {
public:
figure(int startPosition);
void changeImage(std::string);
void dissapear();
void loadImage(std::string);
private:
sf::Image img;
};
figure.cpp:
figure::figure(int startPosition):sf::Sprite(){
}
pawn.h:
class pawn :
public figure
{
public:
pawn(int startPosition);
~pawn();
private:
void move(bool canBeat, bool isAsStart);
};
pawn.cpp:
pawn::pawn(int startPosition):figure (startPosition)
{
}
in main.cpp:
pawn pawn1(position);
sf::RenderWindow window(sf::VideoMode(sets.windowX, sets.windowY), "frame");
window.draw(pawn1);

Try this
class figure : public sf::Sprite
Inheritence for classes is private by default.
