A siddur using feminine language for God?

Shavua tov everyone! I’ve been thinking about this poll where the majority of this sub viewed Hashem as beyond human notions of gender. There was quite a lively debate in the comments about how Jewish texts and prayers nevertheless exclusively refer to God as הוא, אתה, a father, a king, etc.

So my question is, has anyone encountered a siddur with prayers that refer to God some or all of the time with feminine pronouns, adjectives, or terms? Is anyone part of a community that prays from such a siddur? If a siddur like this exists, I would like to see it or hear about your experiences with it!
