Edit videos before uploading

Idea name: Edit videos before uploading
Description: Not always when we record a video and we want to show it to our friends and family we want to send it the way it is; change the speed, crop it, adding texts, stickers and other things is very useful, in addition to being considered a feature-rich function.
Target user: All users
Why this is important: The video upload feature is currently unavailable, but this will change in the future. My intention is to request a more robust feature. Recently, Telegram added considerable improvements to the video editor feature; resources such as those mentioned would value the Status in addition to making it a private and secure option to Telegram in features.
Any other comments: The image below does not represent a request for all the features mentioned in the image.
