Telegram - AutoInvite members to my own groups

My business: I created a Telegram group to develop post engagement (likes, comments) on Instagram. One member publishes link of their post, the others must like or comment before publishing in their turn. The group is regulated by a bot that ensures the respect of the rules. We are currently +200 members on the group of which 70 are regularly active. What I need: Increase the community that regularly uses the group and exceed the 500 active members. For this I need to get a JS script or software to automatically invite members of "competing" Telegram groups or send DM. I understood that the complexity was to rotate Telegram accounts that invite, use dedicated proxies and put a sufficient amount of time between two invitations to not be seen as spam by Telegram.
