What 'supporting documentation' should my parents-in-law bring for B2 visa interview in regards to financials/income?

I read the https://www.visajourney.com/guides/visitor-visa/, but I am still unsure what supporting documents I should advise them to bring for establishing the financial/income requirements.

 

For a bit of background, my wife (K-1 Visa / Pending GC Decision) wants her parents to come visit sometime in 2026, which I believe should be fine given they have ample evidence of ties to Philippines (e.g. taking care of family members, owns a home, owns multiple plots of land, etc.), no criminal background, no prior visa/immigration issues, etc. However, the problem comes in regards to financial/income requirements as they are basically retired other than some part-time selling of crops, so on paper, no income.

 

Now I know unlike K-1 Visa, there is no actual connection to myself or even my wife in regards to the application, so no need to provide an Affidavit of Support, but realistically, we would be supporting them when they come to visit and we would be paying for all their travel costs. I'm just curious how to best go about advising them to evidence this plan or if this in itself is a huge red flag that they cannot pay for themselves.
