12:32 PM
hi... yes you can but what you want to do is a bit involved which is why I used the first doc as kind of proof of concept.. To implement this you would really need to review the posted documents... all of which have code snippets showing how to achieve the individual steps required. Combining it all together to have a deployable code base for creating and sharing views programmatically is unfortunately beyond the scope of Google Support. WE are limited in code review and direct recommendations, or writing code for users of the platform mostly for legal reasons — Paddy Popeye 29 secs ago

Get rid of all the unsafe blocks that are just doing pointer casts and you will probably fix quite a few bugs. Then, if it's working, perhaps you could post it on Code Review to get feedback on the other uses of unsafe. If it's still not working, you can post it here after creating a minimal reproducible example. Note that Stack Overflow does require you to post all the code necessary to reproduce the problem, not just a link. — trentcl 35 secs ago
