I know it's a little late but since I was just doing this and looking for information related to the panel I commented:
I'm starting out but to create the logo you can use an image, convert it on this website
https://image2svg.com/
After obtaining it, upload it to your server and after that use a txt record with the name:
txt
default._bimi
value =
to get the value use this page
https://easydmarc.com/tools/bimi-record-generator
and then check it on the same site or in mxtoolbox
