Find item's position in Tag

Do the following then. Forget the blocks above. And let’s do something simpler.
You have a list of 3 products, and these products are as follows:
Tag = Offers
List Product 1 = 1, 78939845678, Product A
Listing 2 Product = 2, 789398456745, Product B
List 3 Product = 3, 78939845655, Product C
This means Product Code, your barcode and your name.
Would you be able to assemble for me the blocks that show me the position of Product 3 in the Offer Tag List?

I edited above review

you might want to prepare a simple example project as simple as possible, so someone can help you

I will do this then and can post here the aia?

The Offer list is this:

Offer: β€œ[[” 123456 \ β€œ,” 7898917294505 \ β€œ,” Uni Maca Peruvian Powder \ β€œ,” \ β€œ,” 150 g \ β€œ,” \ β€œ,” \ β€œ,” Energy and Stamina β€œ,” Unilife " , "35.00 ", "20 ", "1 ", "https: \ / \ / firebasestorage.googleapis.com \ / v0 \ / b \ do-well-3d183.appspot.com \ / o \ / 7898917294505? alt = media & token = 164e32d1-17f8-4cbe-a006-45da70bf5558 \ β€œ], [” 537 \ β€œ,” 7898483537716 \ ", " Uni Luteina ", " ", " 60 Caps ", " ", \ β€œβ€, \ "Natural ", \ "Unilife ", \ β€œ49.90”, \ β€œβ€, "2 ", "https: \ / \ / firebasestorage.googleapis. com \ v0 \ / b \ do-well-3d183.appspot.com \ o / 7898483537716? alt = media & token = 802d3f5c-e80c-4c43-8ca9-b9e6496a4b84 \ β€œ]]”.

How do I find out where 123456 is? I know that it is in position 1 and product 537 is in position 2, but how do I find this position through a search?

In the example below I need Box1 to be 1 if text = 123456 and Box = 2 if text = 537
