Filter Gallery using DropDown and Many to Many relationship

[tatenda2022]

Could you advise on how to filter a Gallery using dropdown and from a many to many relationship.

this is the current filter I am using

Currently experimenting with the above picture. 
I have table 2, as the gallery 1 on the left and table 1 and as gallery 2 on left.
I am using the dropdown to filter gallery 1. which shows data on Gallery 2 (Gallery1.Selected.'Standard Product Pricelists')

Now I am trying to take out Gallery 1, and just use Dropdown directly to filter Gallery 1. they have a many to many relationship between the 2 tables. but I can't workout how to do it

I have tried using this

LookUp('Bundle Databases', 'Bundle Name' = 'Product Name').'Bundle Name' , but no luck

Table 1(List has All items) = Gallery 2

Table 2 (Bundle Database) in Gallery 1

Dropdown is based Bundle Name Column
