Python/Selenium web scrap how to find hidden src value from a links?

Scrapping links should be a simple feat, usually just grabbing the src value of the a tag.

I recently came across this website (https://sunteccity.com.sg/promotions) where the href value of a tags of each item cannot be found, but the redirection still works. I'm trying to figure out a way to grab the items and their corresponding links. My typical python selenium code looks something as such

all_items = bot.find_elements_by_class_name('thumb-img')
for promo in all_items:
    a = promo.find_elements_by_tag_name("a")
    print("a[0]: ", a[0].get_attribute("href"))

However, I can't seem to retrieve any href, onclick attributes, and I'm wondering if this is even possible. I noticed that I couldn't do a right-click, open link in new tab as well.

Are there any ways around getting the links of all these items?

Edit: Are there any ways to retrieve all the links of the items on the pages?

i.e.

https://sunteccity.com.sg/promotions/724
https://sunteccity.com.sg/promotions/731
https://sunteccity.com.sg/promotions/751
https://sunteccity.com.sg/promotions/752
https://sunteccity.com.sg/promotions/754
https://sunteccity.com.sg/promotions/280
...

Edit: Adding an image of one such anchor tag for better clarity:

By reverse-engineering the Javascript that takes you to the promotions pages (seen in https://sunteccity.com.sg/_nuxt/d4b648f.js) that gives you a way to get all the links, which are based on the HappeningID. You can verify by running this in the JS console, which gives you the first promotion:

window.__NUXT__.state.Promotion.promotions[0].HappeningID

Based on that, you can create a Python loop to get all the promotions:

items = driver.execute_script("return window.__NUXT__.state.Promotion;")
for item in items["promotions"]:
    base = "https://sunteccity.com.sg/promotions/"
    happening_id = str(item["HappeningID"])
    print(base + happening_id)

That generated the following output:

https://sunteccity.com.sg/promotions/724
