@gjwgit This PR ready for review. Sorry, the last 2 commits for this PR were inadvertently merged into dev instead of this branch. They updated the GrantPermissionUI examples in README.md and added an assertion check to GrantPermissionUI parameters (that externalWebId is provided if isExternalRes). Then merged dev into the pr branch to resolve conflicts. Those commits can stay in dev, if this PR is approved and merged.
