This does not answer the question well. The ABR (Adobe Photoshop Brush) format does not seem to be recognized by Affinity.
I found a tutorial in French.
Drawing the contour of the tape. Filling: white, 25% opacity. Outline: normal melting, opacity 35%, radius 1 px, inner alignment, white. Internal glow: normal fusion, opacity 19%, radius 215 px, black, noise 46%. Outer shadow: Normal blend, 40% opacity, noise, 46%, 1 px radius, black. Please note that as of February 12, 2021, noise is not supported and cannot be precisely adjusted.

Hi jphthierry,
Thanks for reporting this. I'm logging the issue to be looked at.

Optikz,
i just discovered that AP and AD allow to create complex gradients by adding stop points - select the gradient tool, select the gradient type, click on the gradient icon and than click on the insert / copy / delete buttons to add and remove stop points. for each stop, you can set colour, relative position and ramps. 
the multiple masks method i suggested still works and can be a way to achieve even more complex goals, but working with stop points greatly simplifies tasks like creating gradients that have a reversing or waving shade, even multiple.
 
take a look at this tutorial - it's about designer, but photo works the same under this aspect.

Hi Singapored,
This shortcut (to set foreground/background colours to black/white) is already available.
Go to Affinity Photo Preferences, Keyboard Shortcuts section, Photo | Miscellaneous dropdowns, 5th line: Set Fill to Black and White.

For  those who are interested ....
