Nested svg in Power BI

Hi all!

I'll be thankful for any help or advise. I need to put svg into svg.

I have complex svg containing different elements and numbers in one; one of this elements is yellow rectangular; I need to put some number on this rectangular in the way that right borders of the number and the rectangular are alligned. After some investigation I decided to solve this with using nested svgs: the rectangular will be the new svg inside the original one, and the number will be simply alligned to the right.

The problem is that none of the syntaxes for nested svgs, which I found, work when inside Power BI, my image is always broken. Are there any tips? Thank you
