Hidden input Selenium Python in Div within TD

Background
I am trying to automate a website data input; however, I have not found a way to send the value to the field "___33_xsde_6h_input__data" for the portion of the HTML attached.
I have seen that Selenium is unable to write directly to hidden fields per the question 1, the question 2, question 3 and question 4. However I have not been able to find the specific solution for my scenario.
Code Attempted
HTML

<td class="RND_Input" colspan="1"><div id="RND_generatedId_1" class="RND_FieldDecor">
<div class="RND_MII_Container">
<input type="hidden" name="___33_xsde_6h_input__data" value="RND:null-axxx"><input id="___33_xsde_6h_input__data" class="" type="text" 
value="[not defined]" autocomplete="off">
</div></div></td>


Python:
I have tried most of the solutions to see if the element is being able to be set, without luck

#Attempt 1 by Xpath
inputElement =ObjSelenium.find_element(By.XPATH,'//*[@id="___33_xsde_6h_input__data"]')
inputElement =ObjSelenium.find_element(By.XPATH,'.//input[@id="___33_xsde_6h_input__data"]'
    '/following-sibling::input[@type="hidden"]')
#Attempt 2 by CSS_SELECTOR 
inputElement=ObjSelenium.find_element(By.CSS_SELECTOR,'div.RND_Input>input[type=hidden]') 
inputElement=ObjSelenium.find_element(By.CSS_SELECTOR,'div.RND_MII_Container>input[type=hidden]')
#Attempt 3 by ID
js = "document.getElementById('___33_xsde_6h_input__data').value = 'text';"
ObjSelenium.execute_script(js)


Question
How can I be able to set the HTML element ""___33_xsde_6h_input__data"" within Selenium driver in order to update its value?

Edit: The answer from Undetectable Selenium threw the following (with both approaches)

Solution 1:

Solution:
The thing is that the code was in another frame, I realized it when I tried to update my HTML and realized there were 2 body tags.

So in order to activate the correct Xpath, I needed to activate the frame per this question

ObjSelenium.switch_to.frame(ObjSelenium.find_element(By.XPATH,"//iframe[@name='RND _SubSessioniFrame']")) 
#where RND_SubSessioniFrame is the name of the iframe element associated in the main HTML
inputElement =ObjSelenium.find_element(By.XPATH, '//*[@id="___33_xsde_6h_input__data"]')
inputElement.send_keys("Yay!")

As noticed, I do not set Wait elements here because I did so before going to the previous step with the following.

WebDriverWait(ObjSelenium, 10).until(ObjSeleniumExpectedConditions.presence_of_element_located((By.XPATH, '//*[@id="ButtonShowedAfterLoad"]')))
