As requested, here are the two workflows I use to post likes and replies from my phone.
They both require the 'Likes and Replies' WordPress plugin.
The 'like' flow accepts a URL so needs to be triggered via 'Run Workflow' in the Safari share sheet.
The 'reply' flow accepts text from so should be run from a note-taking app. Write your reply, share it and you are then prompted for the URL you are replying to.
Thy are both set to post as draft for testing purposes, change this to published for a more streamlined experience.
