Certificate for hotel TV

I am developing an app for hospitality TVs, and I aim to install the app on all targeted TVs within hotels. How can I obtain the necessary certificate for this?

I have created a .wgt file following the standard procedure for Samsung TVs and prepared an sssp_config.xml file, which I have placed on my domain server. Using the URL launcher, I attempted to install the app, but encountered an issue; I suspect it may be related to the certificate. How can I acquire the appropriate certificate in this scenario?

Hello

Did you check this page to create the certificate?
