@DylanDylann let me know if you'd need more details in the doc to accomplish this, but should be straightforward since most of the work on this is BE.

[carlosmiceli]

@DylanDylann all good here? Need help with anything?

[DylanDylann]

@carlosmiceli It is straightforward, but I believe that this issue could only be implemented after the BE done

[carlosmiceli]

Will be able to come back to the Downgrades project this week hopefully.

[carlosmiceli]

The BE logic is in review, will notify once it's merged so this can be worked on.

@carlosmiceli mind adding this to a project? Thanks!

[carlosmiceli]

Sure thing!

[carlosmiceli]

@DylanDylann just merged final BE PR :)

[carlosmiceli]

What's the status here @DylanDylann ?

[DylanDylann]

I hold this PR because we need to merge this PR #53343 first, then we can easier to implement this one

[carlosmiceli]

Still holding on the same PR as @DylanDylann mentioned above.

[carlosmiceli]

@DylanDylann Seems like we can unify this issue with this issue (hookup api), right? And we can close this one?

[DylanDylann]

Yes
