I looked in this forum and I found that to instal unverified plugin
I have to go to “Develop your own plugin” option and then paste link like that: https://www.transvribe.com/.
So I did
And I get error that: Couldn’t install plugin.
If i try to go to instal unverified plugin option imidiatly, I also get error: Couldn’t install plugin.
As I understand those unveried plugins are only for 15 developers to use, so I only have option to develop my onw unverified plugin?
