How can I improve speed between buttons tap/click using Selenium Appium python

Support

I’m learning and writing a script to test an iOS app by using a selenium python script with Appium.

But between two button taps/click some time it can be a little bit long, between each execution.

 driver.find_element_by_accessibility_id("Product_Purchase_Button").click()
            time.sleep(0.8)#loading page
            driver.find_element_by_accessibility_id("Check_Box_Button").click()
            driver.find_element_by_accessibility_id("Buy_Now_Button").click()

I would like to know if I can optimize this part of my code, to click/tap instantly the buttons.

Thank you
