How can I place a donation button or link on YouTube?

Good Morning,

I would like to place a PayPal donation button or a donation link on YouTube.

1. So that the donor only needs to click on the button and is then redirected.
2. Preferably directly under the respective video.

Yes, I can add a donation link via General Information; unfortunately, it only appears in the channel description, which is confusing. No, there is no button displayed at the bottom right of the video.
