How to convert blob file to base64 by integromat

Hello my friends, I am a complete beginner in the integromat tool.

I need to send an image file via WhatsApp.

It turns out that I search for this image on an API server via the HTTP Request module.

The module returns the file as blob/bin/hex.

I need to transform this file into base64 so that I can later send it.

I know it is asking a lot, but since I am a beginner, if anyone can share images with great detail, I will be eternally grateful.

I have already racked my brains in several ways but have not been able to find a solution.

Thank you very much in advance.
