How to right click and hold it in selenium python

Unfortunately, this is not supported, but you can modify the source code of selenium in your site-packages directory, it's pretty straightforward since all you have to do is change the parameter for the pointer event in the click_and_hold method, to the same parameter as the pointer event in the context_click method, and then create a custom function for that.

Here's what I managed to do:

File 1: Locate and edit this file in
Lib/site-packages/selenium/webdriver/common/actions/pointer_actions.py

Add this function to the "PointerActions" class:

class PointerActions(Interaction):
    def move_to_location(self, x, y):
        ...
    def click(self, element=None):
        ...
    def context_click(self, element=None):
        ...

    # --- Add this function
    def context_click_and_hold(self, element=None):
        if element:
            self.move_to(element)
        self.pointer_down(MouseButton.RIGHT)
        return self
    # ---
    
    def click_and_hold(self, element=None):
        ...

    def release(self):
        ...
    def double_click(self, element=None):
        ...

File 2: Locate and edit this file in
Lib/site-packages/selenium/webdriver/common/action_chains.py

Add this function to the "ActionChains" class:

class ActionChains(object):
    def __init__(self, driver, duration=250):
        ...
    def click(self, on_element=None):
        ...

    # --- Add this function
    def context_click_and_hold(self, on_element=None):
        if on_element:
            self.move_to_element(on_element)

        self.w3c_actions.pointer_action.context_click_and_hold()
        self.w3c_actions.key_action.pause()

        return self
    # ---
    
    def click_and_hold(self, on_element=None):
        ...
    def context_click(self, on_element=None):
        ...

If the .release() function is not able to release the right mouse button after holding, you should add a parameter to the .release() function by making these changes:

class PointerActions(Interaction):
    def click_and_hold(self):
        ...

    def release(self, button="left"):
        button = MouseButton.LEFT if button == "left" else MouseButton.RIGHT
        self.pointer_up(button)
        return self

    def double_click(self):
        ...

class ActionChains(object):
    def pause(self):
        ...

    def release(self, button="left", on_element=None):
        """
        Releasing a held mouse button on an element.

        :Args:
         - on_element: The element to mouse up.
           If None, releases on current mouse position.
        """
        if on_element:
            self.move_to_element(on_element)

        self.w3c_actions.pointer_action.release(button)
        self.w3c_actions.key_action.pause()

        return self

    def send_keys(self):
        ...
