Hi,
Im new to power apps.
I have my data in dataverse in two tables.
My main table is Documents that a have a relationship one to many with my other table "Providers"
1º Table, Documents Table:

2º Table Fornecedores( Providers) table:

I'm have 2 issues:
1- In the image bellow I'm trying to build a Gallery, my Data Source is my First Table (Documents table).
I'm trying to use ThisItem.Fornecedores in Text property of a subtitle box in a image gallery but Is not working.
For normal columns it works because they are part of the main table, but "Fornecedores" (providers) is column bind by a relationship coming from my second table, so it's not working.
What can I do?

2º Issue:
I'm trying to build a dropdown filter bind also bind to my Fornecedores field (Providers).
I'm using fuction Choices on items property and it works for the normal columns in my First Table. But the relationship Column (Fornecedores) shows the 4 options, but they're not appearing.
