genome resource of other species

[pengxin2019]

Dear ArchR development team,
I am handling scATAC data of other species. (neither human nor mouse).
From the document of addArchRGenome function, I realize that it is possible to create this global environment variable representing the genome: https://www.archrproject.com/reference/addArchRGenome.html

Taking createArrowFiles as example, https://www.archrproject.com/reference/createArrowFiles.html
It seems like both the input of the getGeneAnnotation and getGenomeAnnotation is an ArchRProject object. But I did not find the function to create this ArchRProject object using a non-ArrowFiles. I find ArchRProject but is requires a ArrowFiles as input. I can query the gene annotation from other packages like AnnotationHub but I do not know how to make it to be a ArchRProject object.

Also, in terms of createGenomeAnnotation at https://www.archrproject.com/reference/createGenomeAnnotation.html
If I remember correctly, the source of the BSgenome is UCSC not ensembl which is what we preferred in terms of the species we are working on. It seems like only a BSgenome object could be accepted by createGenomeAnnotation. Providing the http to the gtf file of the genome or annotation would not work, right?
Is creating a BSgenome by myself the only solution that might work?

Thanks
Best
PENNY
