How to display blocks on all website pages?

Hi! I wanted to add some blocks (an image of 3 total) to the bottom of each page, directly above the footer. See included image. The only issue is I want these 3 images to appear on ALL of my pages - collections, product pages, etc. I cannot find anyway to make blocks that appear on the home page, to appear on other pages.

Does anyone know how?

I do have a paid theme (not shopify) called district. Do I have to switch themes to make this happen? Contact the theme “maker”…as this area is completely not my thing. Any help or advice would be appreciated. Thanks in advance!

@GiaRoma - please first take backup of your theme and then you can add the required section in above screenshot in the theme.liquid page just before your footer code.

This way this section will appear on each and every page and you can edit form customize settings.

That worked. Thank you so much!!!

@GiaRoma - great, do let me know if you need any updates later.
