Can we retrieve JWT in the response to the User SignIn when using .NET Xumm SDK ?

Is there such a thing as a deeplink that would return the client back to a Telegram Group after that sign with the Xaman application?

So this is more a general question, in simple terms i am building an app that takes one transaction and lets say splits it into 3, a little bit like the carbon off set - so i have a smart contract on the xahau network.

Is there a way to lock up issued tokens on the XRPL blockchain?

Is there a way to check a pending "Signed Request" and kill that payload? If have a situation whereas the request is submitted, but the user doesn't sign and submits another one. I suppose it's fine to let these expire on their own, but seems a little wasteful and would like to kill those previous request if followed by new request using the same r-account.

I have a situation whereas I need to pull the URL returned from the createAndSubscribe event and right now it's posting the URL to my endpoint over and over whilst waiting for the signature. Is there another way I can just say, "hey, here is my sign SignIn payload, grab the URL and send it to the user for signing, but like I need to wait for the signing within the event. Does that make any sense at all?

Up until now i have been using the Hook services to generate the accountID but how do i generate it in my app, i have gone through the various xrpl libs available and have yet to find anything - so is there utility in a lib somewhere to help with this ?

Currently, I am facing the error 'Max payload of 1587 exceeded.' I want to increase my rate limit.

I am looking to up setup a set trust line feature using the QR code similar to xrp services. Does anyone have any resources on how to do this?
